Friday the 13th is an American horror slasher franchise created by Victor Miller and Sean Cunningham. Set largely around the fictional small town of Crystal Lake, New Jersey, it tells the story of serial murderer Jason Voorhees, and others who would kill on his behalf and in his name. Neglected and bullied as a young boy, Jason is believed to have drowned at Camp Crystal Lake while the counselors responsible for his well-being were off making love, but decades later he returns to the camp with bloody vengeance as his sole motivating factor.
