The ultimate social experiment begins when seven beauties and seven geeks move into an enormous mansion in Los Angeles. After choosing teams, Brian explains the first challenge, where the women and the men must learn from each other to complete tasks. All of the contestants must rediscover the fifth grade; the women compete in a "spelling bee-esque" trivia contest, focusing on history, spelling, and geography. Meanwhile, the men learn dance moves from the women, who then must perform in front of a crowd of people, who judge who danced the best.

Episode two brings strain to the game – some of the Geeks are already growing thin on the Beauties, and one pair in the house, Erika and Brad, begins a romance. The second set of tasks entails lots of oil – the women must complete a series of tasks having to do with a car: popping the hood and changing the oil, air filter, and a tire. The men are forced to brush up on massages. Fighting breaks out between the two because of Chuck's inability to nominate anyone for elimination.

The third set of tasks is one of the trickiest yet for both groups - the Beauties and the Geeks. The women must brush up on their rocket science and follow a series of instructions in order to assemble a rocket and launch it in the fastest time. Later, the men are taken to a series of stores in order to purchase three outfits - formal wear, swimsuit, and casual wear - for their partners to wear in a fashion show.

The competition heats up as the four remaining teams gear up for their new tasks. The ladies get to give the guys makeovers and the guys must go out and get phone numbers from total strangers.

For the first time, the individual couples must work together as a team to have a successful night of camping. The rivalry between Chuck and Richard reaches an all-time high, Scarlet gets very upset at Shawn for getting sick during the challenge, and the romance between Scarlet and Chuck seems to fizzle out because of the competitive fire in Scarlet

During the final day at the mansion, the teams spend more time getting to know each other, learning a skill that the other excels at - karate, cooking, kayaking, and piano - as one last thing to do with each other before the final elimination, there is a series of ten questions about your partner.

Beauty and the Geek's first season contestants gather in front of a live studio audience to discuss their time in the house, as well as what they took away from the experience, how their confidence has increased, and how their rivalries and romances have ended after the show has wrapped production.
