Marshall Seymour (Judge Reinhold) 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 (Fred Savage). 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. And as if that weren't enough, a pair of smugglers are in pursuit of the skull.
