Documentary filmmaker Louis Theroux continues to explore some of the more unusual aspects of American society by looking at how modern America deals with birth, love and death. List of episodes: "Love Without Limits" - Louis travels to Portland, Oregon which is seen as the U.S. capital of polyamory and ethical non-monogamy. He embeds himself with families who have opened their relationships to others. "Choosing Death" - There are now 6 U.S. states that offer the terminally ill the option of ending their lives with a prescribed cocktail of drugs. In California Louis meets some of those planning to end their life and some who don't meet the criteria. "Take My Baby" - Louis explores open adoption in California, where women hand over their babies at birth to adoptive families paying tens of thousands of dollars for the privilege.
