Hockey-masked psychopath Jason Vorhees is back in business at Camp Crystal Lake in the fourth (but far from final) installment of the popular horror franchise. As randy teens are slain one by one, Tommy Jarvis (Corey Feldman) concocts a plan to distract the killer. Makeup master Tom Savini provides much of the wince-inducing gore, and actor Crispin Glover turns in an atypical performance as a stud in training.
