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.
