For the summer, troublemaker Freddie Egan is being sent to a camp-style juvenile detention center, while spoiled rich-kid Frederick Egan III is going to a luxurious getaway for kids of the elite. Until a name mix-up at the bus-boarding area sends the boys to each other's destinations, and while Eddie gets a taste of the good life, Frederick has to deal with being without all his usual comforts. Eventually, they both learn some valuable life-lessons.
