Tobe Hooper's influential cult classic continues the subgenre of horror films based on the life and "career" of Wisconsin serial killer Ed Gein, which began with Alfred Hitchcock's own influential cult classic Psycho. When Sally Hardesty (Marilyn Burns) hears that the Texas cemetery where her grandfather is buried has been vandalized, she gathers her wheelchair-bound brother Franklin (Paul A. Partain) and several other friends together to see if grandpa's remains are still in one piece. While in the area, Sally and her friends decide to visit grandfather's old farmhouse. Unfortunately, a family of homicidal slaughterhouse workers who take their job home with them have taken over the house next door. Included amongst the brood is Leatherface (Gunnar Hansen), a chainsaw-wielding human horror show who wears a face mask made out of human skin. Sally's friends are rapidly exterminated one-by-one by the next-door neighbors, leaving only Sally left to fight off Leatherface and his clan.
