Who would believe it - the Baby-sitters have won the lottery! And with their winning money, the girls are all going with Dawn to... California!
What adventures they have. Jessi lands a (tiny) part in a TV show, Kristy gets into a kind-of-fight with Dawn's We Love Kids Club, and Stacey turns into a surfer girl! And in between all that excitement, they still have time for baby-sitting, sight-seeing, and the beach.
How can they go back to Stoneybrook now that they've turned into California girls?
