Friday the 13th (1980): classic slasher at Crystal Lake.

A classic slasher film set at a summer camp at Crystal Lake that is to reopen two decades after a brutal double murder. Steve Christy invites a group of young people to help get the camp ready for the summer season. But the idyllic setting is deceptive: an unknown killer strikes even before the first campers arrive, and Alice, Bill, Brenda, Marcie and Jack are also in his sights. It was directed by Sean S. Cunningham and stars Betsy Palmer, Adrienne King, Jeannine Taylor and Kevin Bacon.
