Friday the 13th Part 2 (1981)

Five years after the horrible bloodbath at Camp Crystal Lake, it seems Jason Voorhees and his demented mother are in the past. Paul opens up a new camp close to the infamous site, ignoring warnings to stay away, and a sexually-charged group of counselors follow -- including child psychologist major Ginny. But Jason has been hiding out all this time, and now he's ready for revenge.
