The ultimate social experiment makes the move from the safety of a mansion to a beach-side paradise in Fiji, where eight new beauties are paired up with eight new geeks. After they spend a night out of their comfort zone in an open tent, the geeks have to channel their inner warrior when they perform a Fijian war dance in front of a real-life tribe, with the winner receiving a surprise package, while the beauties are tested on their English skills in a spelling bee where one incorrect answer sees their geek's undies filled with live crabs. The winners of the two challenges each nominate a team to send to the Elimination Room, where they compete in a quiz in which the team with fewer correct answers is eliminated.
