"Eddie's ready for the holidays. But are the holidays ready for Eddie?"

Though Eddie's fired right at Christmastime, his boss sends him and his family on a South Pacific vacation, hoping Eddie won't sue him after being bitten by a lab monkey. When the Tuttle family winds up trapped on a tropical island, however, Eddie manages to provide for everyone and prove himself a real man.
