Before the sequels, spin-offs, and even the iconic hockey mask, this is the fright flick that helped usher in an entire era of ‘80s horror films. The story begins in 1958, as a couple of horny camp counselors get their freak on instead of preventing a kid named Jason from drowning in Crystal Lake. They’re mysteriously murdered, years pass, and now a fresh batch of foolish kids (including a young Kevin Bacon) aim to reopen the camp. The only problem: a ruthless machete-wielding psychopath has other plans. One by one, the kids discover first-hand what happens when you wander off in the woods alone. Here’s a hint… it’s not called a “slasher movie” for nothing.
