Marshall Seymour is an Executive Vice President for one of Chicago's most prestigious department stores. He is also a divorced, stressed-out workaholic with little time for his 11-year-old son, Charlie. But when the two find themselves under the influence of an ill-gotten mystical skull, they become much closer...mostly due to the fact that their minds have switched bodies! Now a preteen boy is up against backstabbing co-workers, politically dangerous board meetings and a blossoming love affair - while a grown man is forced to contend with grade-school bullies, homework and a surprising scarcity of Evian water in the school cafeteria.
