Cryptozoologist Doctor Peña traps the legendary Chupacabra on a remote Caribbean Island to make his name in the scientific community. When he smuggles it aboard the cruise ship Regent Queen, commanded by Captain Randolph, the monster breaks out of the cargo hold and makes a smorgasbord out of the passengers and crew.
