Twenty years after a young boy named Jason Voorhees drowned at Camp Crystal Lake due to the negligence of two amorous counsellors — who were subsequently murdered by an unknown killer — a group of horny teenagers arrives to reopen the camp, and soon find themselves being dispatched in gorily inventive ways. Inspired by John Carpenter's Halloween, producer-director Sean S. Cunningham's low-budget blockbuster launched one of the most successful and longest-running horror franchises of all time and spawned one of modern horror's most iconic villains: Jason, a machete-wielding, hockey mask-wearing killing machine with a knack for revivification. But if that's the only Jason you know, you're in for a surprise in this shocking first installment of the series, which offers a considerably different version of everyone's favourite mute maniac.
