Mark travels to the US and Brazil to meet three people who have taken plastic surgery to new extremes. In Los Angeles he meets Jenny Lee, a real life Texan Barbie doll, who has had 44 plastic surgery operations, including a brow lift, eyelid lift, lower eyelid lift, four nose jobs, cheek implants, three breast enlargements, and full body lift. In recent times Jenny has been diagnosed with Body Dysmorphic Disorder. Brazilian model Angela Bismarchi holds Brazil's record for the most plastic surgery. Her first husband was a plastic surgeon. And her second husband too. Brazil's answer to Jordan, the 37-year-old model has undergone virtually every cosmetic procedure imaginable, but as a gift to her current husband Wagner she even had a hymenoplasty, so she could be a virgin again before they married. In the Nevada desert, Mark meets Denis Avner - also known as `Stalking Cat' - who has spent the last 20 years having surgery, often without anaesthetic, in a bid to turn himself into a tiger, including facial modifications to give him pointed ears and caps to give him fangs. Recognised by Guinness World Records as being the most surgically modified man in the world, Cat has also had the shape of his brow and forehead radically altered, and facial implants to allow him to wear whiskers. Mark sets off with Cat on a road trip to Las Vegas, where Cat aims to begin a new life for himself, and on the way new truths come to light about Stalking Cat's story.
