All in all Louis was $4,590 up from $3000 at the end of what he called his "blowout night" playing Baccarat in addition to turning $500 into $700 on his first foray into gambling at the Blackjack tables. As an interesting aside, the money gambled was his own, not part of the production budget.

Summary: In the first episode of this two-part series, Louis spends time in one of the most notorious sections of Miami County Jail - the fifth and sixth floor of 'Main Jail', where many of the most volatile inmates are incarcerated. Held in large cage-like dwellings for up to 24 men, the inmates have developed a strange and violent jail culture. The men - who remain in the cells almost all the time and may only leave for yard time twice a week - live under the sway of a gladiatorial code. They fight each other for food, for status, and often just to pass the endless hours of confinement. Trips to the infirmary are a frequent occurrence as inmates are viciously attacked and beaten, but the guards say they are powerless to end the abuse.

Summary: Louis Theroux concludes his exploration into Miami Mega-jail, one of America's largest and most violent of jails, a holding pen for almost 6000 un-convicted inmates.

Summary: America's love affair with prescription painkillers has led to widespread dependency on opiates. But following a crackdown on their over-prescription, where does this leave the two million Americans who have developed a habit for these high-strength painkillers? With the pills now becoming increasingly expensive and scarce on the black market, vast numbers of Americans have turned to the cheaper and stronger opiate - heroin. The drug now claims more lives in the US than either car accidents or gun crime. And, for the first time in over two decades, life expectancy in the US is declining - largely attributed to the rise in fatal heroin overdoses. In Huntington, West Virginia, Louis Theroux embeds himself in an Appalachian community that is being devastated and stretched to its limits by widespread heroin use. With one in ten babies in the city born dependent on opiates and a fatal overdose rate 13 times the national average, this is the epicentre of the most deadly drug epidemic in US history. Louis spends time with the user community caught in the vice-like grip of drug misuse and follows the emergency services struggling to cope with multiple overdoses each day.

Summary: Houston, the fourth largest city in the US, is widely considered to be the number one hub for human trafficking in North America.

Louis also embeds with law enforcement on undercover operations and meets Vice Division officers tasked with persuading the working women to speak out against their pimps.

Summary: Milwaukee is said to be one of the most racially divided and impoverished cities in the US. With spiraling gun crime and homicide rates, this Midwestern city encapsulates America's complex and troubled relationship with guns and the increasing disharmony between African-American communities and the police. In this episode, Louis spends time with the Milwaukee Police Department as they patrol District 5, home to some of the nation's deadliest streets, with a homicide rate over twelve times the national average, and follows the homicide division as they investigate one of the city's many killings. He also embeds with a family who have recently lost a loved one to gun crime, and he meets a local social activist, once a criminal and gang leader herself, who has turned her life around and is coming up with her own solution to the blight of gun crime. On the streets of Milwaukee, Louis discovers a community who is often misunderstood by, and mistrustful of, the police. Arriving at a time of heightened tension between the police and the African-American community due to a recent police shooting, Louis hears from both sides of the debate and uncovers hope in a desperate city.

Summary: Anorexia, the pathological fear of eating and gaining weight, is now the most deadly mental illness in the UK, affecting around one in every 250 women at some point in their lives. In recent years, the number of people being admitted to hospital because of their condition has risen dramatically but with many struggling to make a full recovery, being diagnosed with the eating disorder can sometimes mean a life-long battle. In this film, Louis Theroux embeds himself in two of London's biggest adult eating-disorder treatment facilities - St Ann's Hospital and Vincent Square Clinic. He meets women of all ages and at various stages of their illness, accompanying them through an enforced daily routine of scheduled eating, weigh-ins and group therapy sessions. As he spends more time with patients both on and off the wards, he witnesses the dangerous power that anorexia holds over them, leaving some unsure about whether recovery is achievable or even wanted. And as Louis seeks to understand what lies behind this mysterious illness, he finds himself drawn into a complex relationship between the disorder and the person it inhabits.

Summary: For hundreds of years, romantic relationships in western society have been based on the idea of monogamy - two people, together, for ever. But with nearly half of all US marriages ending in divorce, perhaps the traditional model is no longer fit for purpose. In Love Without Limits, Louis travels to Portland, Oregon, the heart of a movement seeking to rewrite the rulebook on how we conduct intimate relationships and experience family life. Portland, whose city motto is 'Keep Portland Weird', is seen as the US capital of polyamory and ethical non-monogamy, the practice of openly and transparently having multiple relationships that go further than just sex. Louis embeds himself with families who have made the bold decision to open up their relationships in a number of different ways, whether inviting others into existing relationships or allowing partners to seek romance elsewhere. He discovers that for many, more partners means more love and more happiness. But for others, multiple relationships have led to jealousy, upset and broken hearts.

Summary: In the US, there are now six states that offer the terminally ill the option of ending their lives with a prescribed cocktail of drugs. Louis heads to California, one of the latest states to adopt this law, where residents can now take home a lethal overdose as long as they are terminally ill, of sound mind and strong enough to administer their own prescribed dose. Here, Louis is invited into the family homes of those who want control over ending their own lives. But he discovers that when you have complete autonomy over your own death, choosing the right time is not such a simple decision. Louis also meets a group who provide information about how to die to those who don't fit the legal criteria. With them, he meets a woman planning to end her life long before what would appear to be her natural time, raising complex moral and legal questions about how much control we should have over our own deaths.

Summary: Louis Theroux heads to California, the US adoption capital, where the majority of newborn adoptions are carried out privately, creating a multimillion dollar industry. Agencies, facilitators and lawyers can earn thousands of dollars per baby by matching up pregnant women prepared to give up their newborns with adoptive parents willing to pay up to $50,000 for the privilege. Louis spends time with the birth mothers preparing to hand over their own flesh and blood, uncovering the stories of poverty, addiction and abuse that can push these women into making such a heartbreaking decision. He also meets the adoptive families, paying out huge amounts of money in the hope of being able to raise a child they can't have by natural means - but in a system open to abuse, whether the birth mum hands over the baby hangs in the balance until after the birth.

Summary: Louis Theroux heads to American college campuses and comes face-to-face with students whose universities are accusing them of sexual assault. As reports of sexual violence have dramatically increased in recent years, the government has urged US colleges to enforce a stricter code of sexual conduct amongst students. Employing specialist administrators to carry out investigations into alleged misdemeanors, they now have the power to permanently exclude those they deem ‘responsible’. For the victims of sexual assault these new processes, which require less stringent levels of proof than criminal cases, have allowed accusations that might have never been heard in a court of law to be vindicated. But alleged perpetrators believe the attempt to be more vigilant about rape and assault has turned into an overreaction that tramples on due process, and harms innocent people. At the start of this journey, Louis meets a neuroscience major called Saif Khan, who has been accused of raping a fellow student. His University is investigating the claims separately even though Saif has been found not-guilty in a court of law. Though Saif continuously pleads his innocence, Louis is drawn into an increasingly complex world, where separating fact from fiction becomes increasingly challenging. He also meets young women whose claims of sexual assault have previously fallen on deaf ears, who believe that a new approach to handling allegations of sex crimes is not only necessary but long overdue. One such student is Mollie Johnson, whose experience is a powerful reminder that there is now a broader understanding of what sexual assault looks like.

Summary: Louis Theroux returns to the UK to spend time in specialist psychiatric units which treat mothers experiencing serious mental illness whilst allowing them to live alongside their babies. Immersing himself on the wards, he meets women who have been admitted with a range of serious conditions - including depression, anxiety and psychosis - often triggered by birth or the strains of motherhood. As he follows the patients and their families both in hospital and recovering back at home, Louis explores what lies behind their recent crisis and discovers the immense challenge in caring for two people in the most vulnerable state of their lives.

Summary: Thirteen years since first encountering one of America's most notorious hate groups, award-winning film-maker Louis Theroux makes a long-anticipated return to Kansas to spend time with the Westboro Baptist Church - a hugely-controversial Christian ministry that for years has picketed at military funerals and other high-profile events with deliberately provocative and homophobic placards. Immersing himself in the strange world of Westboro, Louis explores what happens when a hate-group largely populated by one family loses its patriarch.

Summary: Louis Theroux meets the women legally participating in the new sexual economy, exploring whether selling sex can ever be a healthy way to make money.

Summary: Since making his television debut on TV Nation in the mid-90s, journalist and film-maker Louis Theroux has become synonymous with documentaries involving subcultures and people on the fringes of society. In the first episode of this career retrospective, Louis looks back at his earliest documentaries and explores how some people’s most fervent beliefs can bring them into conflict with mainstream society. From his Weird Weekends episodes on survivalists and UFOs to his now notorious documentary about the White Aryan Resistance in California (Louis and the Nazis), Louis has always been drawn to those whose beliefs seem unusual, confused or, in some cases, abhorrent. Louis catches up again with some of his previous contributors, including Mike Cain, who he first met in the mid-90s, having moved to the hills of Idaho and armed himself for what he saw as an inevitable war with the federal government. Over 20 years later, his views haven’t changed much – but in Donald Trump, he has a president who finally speaks to him. Louis also tracks down Lamb and Lynx, once members of the white nationalist pop group Prussian Blue. They have since rejected their past and believe their story gives hope that even the most indoctrinated can change their beliefs.

Summary: Louis explores how America has managed to take our darkest desires, commodify them and turn them into a saleable product. From his memorable Weird Weekends episodes on porn and rap to films about Las Vegas and the US opioid crisis, this episode explores a very human tendency to jump to the dark side when seeking out pleasure – whether through indulgence, risk-taking or the joy of doing something seen as ‘bad’ or 'wrong’. Louis re-connects with porn-star JJ, who over 20 years ago was just making his way in the adult industry but has since turned his back on that world in favour of a new life in eastern Europe. And Louis catches up once more with Katilia from Heroin Town, whom he last saw hopelessly addicted to drugs, with little sign of turning her life around.

Summary: Louis reflects on the criminal justice system in the USA, which has more prisoners than any other country in the world. In documentaries such as Behind Bars and Miami Mega Jail, Louis spent time with hundreds of incarcerated men, discovering a world with its own rules and codes and a system that seemed to be broken. In A Place for Paedophiles, Louis came face to face with those responsible for serious sex crimes against children who were being locked up indefinitely, even after their sentences had been completed. Louis also revisits his documentaries in Philadelphia and Milwaukee, where tensions between the African-American community and the police were already at boiling point, years before the recent killing of George Floyd.

Summary: Louis examines how the greatest source of love in our lives – our families – can often be the cause of our deepest pain. In his trilogy of documentaries centred around the Westboro Baptist Church, Louis explores the price the family was paying for its devotion to the distorted vision of its patriarch, Pastor Fred Phelps. With Pastor Phelps now dead, the family has been torn apart – some of its members are still utterly devoted, whilst others have left, forbidden from ever contacting their families again. Louis also reflects on how physical and mental health or forces beyond our own control can threaten to derail our family lives. He catches up with contributors from Trans Kids and A Different Brain to see how life has changed since he saw them last.
