Ten-year-old Andy Ohman is spending his summer working at the Aksarben City Zoo where his dad is curator. There are rumors that the city might close the zoo due to budget cuts. An anonymous donor has given the zoo an antique animal carousel, and Andy's dad is hopeful it will help boost attendance. Andy's doubtful that an old kiddie ride will make a difference. He doesn't see what's so special about it. But when he takes it for a spin, he unlocks the magic that will help save the zoo.
