Kristys mum is getting married and everyone is coming to town to help, bringing their kids with them. Fourteen kids! Kristy is sure she and Stacey, Claudia, Mary Anne and Dawn can handle it, they are professional babysitters after all and Kristys mum has offered them a lot of money to take on such a big job. But will a week of changing diapers, stopping fights, solving mixups and keeping fourteen children entertained prove to be too much for the BSC? Can they keep things under control for Kristys big day?
