R | 1h 27min | Horror, Mystery, Thriller | 1 May 1981 (USA)

Mrs. Voorhees is dead, and Camp Crystal Lake is shut down, but a camp next to the infamous place is stalked by an unknown assailant. Is it Mrs. Voorhees' son Jason, who did not really drown in the lake some 30 years before?

After killing Mrs. Voorhees, who was avenging her son Jason's death, Alice Hardy can finally sigh with relief. But there is just one problem. Jason never drowned at Camp Crystal Lake and lived in the nearby woods as a hermit all this time. The day that Alice beheaded his mother, Jason saw everything and his heart filled with thirst for revenge. Two months later, Alice gets stabbed by an ice pick in the temple and disappears. Is Jason behind this? Five years later, a camp next do to Camp Crystal Lake is built and the counselors start snooping around the old, abandoned camp ruins. This makes Jason very upset, since his shack is next to the remains of Camp Crystal Lake and what is inside the shack shall be kept secret forever, even if it means killing nine people!

Synopsis by Brian J. Dillard

Two months after the events of the original Friday the 13th, Alice (Adrienne King), the lone survivor or Mrs. Vorhees' killing spree, meets a grisly end in her city apartment. Five years later, a new group of co-eds converges near Camp Crystal Lake, scene of the original massacre and the drowning of Jason Vorhees that preceded it. This time around, the horny collegians attend a nearby training school for camp counselors. As half the group parties in town, an unseen assailant picks off the other half one by one. Only when camp leader Paul (John Furey) and his girlfriend, Ginny (Amy Steel), return to camp do they uncover the identity of their stalker -- none other than Jason (Warrington Gillette) himself, alive but grotesquely deformed as a result of his childhood drowning. Flashbacks chronicle Jason's behind-the-scenes activities in the first film (perhaps explaining how his mother was able to throw the dead bodies of muscular youths through windows with such apparent ease). The young couple's only hope to defeat the fiend lies in psych major Ginny's insights in Jason's mental state.
