The hilarity begins when professor Sherman Klump finds romance with fellow DNA specialist, Denise Gaines, and discovers a brilliant formula that reverses aging. But Sherman's thin and obnoxious alter ego, Buddy Love, wants out...and a big piece of the action. And when Buddy gets loose, things get seriously nutty.
