The murderous spirit of Jason Vorhees lives on in this horror sequel, although the plot hinges on the mystery of whether the killer's body actually survives. Opening with a nightmare prologue in which Corey Feldman reprises his role as Tommy Jarvis, the boy who killed Jason in the previous installment, the film jumps forward several years to when a teenaged Tommy (John Shepherd), haunted by visions of Jason returning to life, moves into a group home for mentally disturbed kids. Almost as soon as he arrives, Tommy witnesses the death of Joey (Dominick Brascia), an overweight, annoying boy who is hacked to death by psychopathic patient Vic (Mark Venturini). Although Vic ends up safely behind bars, other bodies begin to turn up -- more than 20 by the end of the film. Tommy's own violent streak, displayed when he lashes out at a fellow resident, makes him a suspect; he even doubts his own sanity. But as the bloodshed continues, Tommy finds himself allied with Reggie (Shavar Ross), the grandson of one of the home's employees, in a desperate bid to survive the carnage and find out who the killer behind the hockey mask really is. The producers of the Friday the 13th series actually planned to end it with Friday the 13th -- The Final Chapter, but the box-office success of that film paved the way for the series to continue.
