Immediately after his mysterious escape at the end of Friday the 13th, Pt. 2, Jason Vorhees (Richard Brooker, the third of many actors to fill the role) kills a hardscrabble store owner and his nagging wife before heading back to Crystal Lake, this time to terrify rich girl Chris (Dana Kimmell) and her band of summer-cottage guests. Chris, it seems, is haunted by an earlier encounter with Jason, and her romantic entanglements with local boy Rick (Paul Kratka) do little to ease her nightmares. Meanwhile, the gruesome antics of Shelly (Larry Zerner), a chubby practical joker who just wants to be loved (and get laid), leads to an escalating case of the boy who cried wolf. When he's not incurring the wrath of leather-clad motorcyclists, he's annoying the other guests with his mock mutilations. Soon, stage blood turns to real as guests and bikers alike fall prey to the killer lurking in the barn out back. ~ Brian J. Dillard, All Movie Guide
