The Baby-sitters are running a day camp for kids in Stoneybrook. Campers will do art projects, go on field trips, and even put on a circus show. Then Mary Anne’s father announces that he will be going away for two weeks on business. Great! Mary Anne, Dawn, and Dawn’s mother can’t wait to be “bachelor girls”. But things are not turning out the way Mary Anne had thought. She misses her father a lot. The kids at Camp BSC are choosing sides against each other. And then Mary Anne sprains her ankle. Will Mary Anne cheer up in time to enjoy the rest of Camp BSC?
