Friday The 13th (1980)

Notable as among the first in a very long series of slasher flicks, with effects by Tom Savini. A New Jersey camp reopens after it's been closed for 20 years after a history of accidental deaths. And the horror begins again. Six would-be counselors arrive to get the place ready. Each is progressively murdered: knifed, speared, and axed. Followed by numerous, equally gory sequels.
