Donna organizes the Alpha House "Sex Out" Slumber Party, at which people are urged to take a 24-hour celibacy vow to promote safe sex through abstinence. Clare bets Steve he won't fulfil his pledge at the party and does her best to wear down his willpower. Joe plans to drop out of school upon bad news from his coach. Valerie sets up Ginger with Jonathan to get her off David. When this plan fails, she asks David for a big favor. After emptying Colin's stash, Kelly seeks the cocaine source herself - and hits bottom.
