Joe, a film director, is shooting a horror movie on a remote island with his crew. A critical error, however, leads them to the wrong location—a mysterious territory inhabited by creatures that should never be disturbed. When Joe finds himself in need of extras, the crew encounters these "inhabitants," mistakenly believing they were summoned by Opie. Unsuspecting, the crew treats the creatures just like ordinary extras—until the situation takes a turn that is both tense and absurd.
