It's the penultimate day of the experiment and the heat is on to win badges. The Outsiders are charged with upcycling three cars that have been abandoned in the woods. But which new design will David deem the most useful addition to camp - a drum set, a ping pong table or a hair salon? Next up, it's the Couples Therapy badge with Alan Davies, Judi Love and Laura Smyth each taking a turn at being a therapist for an opposing team. But which team comes out stronger? Lastly, David gives the Outsiders the opportunity to exile the things they don't want from their new post-apocalyptic society. Noisy eaters, procrastination and singing along to songs are all in line for the chop! But who will David agree with most and more importantly, who will win a badge? At the end of the day, the Outsiders head to David's HQ to discover who has done enough to win one of his coveted badges.
