The movie X, also known as The Toolbox Murders, was directed by Dennis Donnelly and released in 1978. It tells the story of a group of young actors and actresses who travel to a remote farmhouse in rural Texas to film an adult movie. Once they arrive, they are greeted by an elderly couple named the Allens, who offer to let them stay in their guesthouse.
As filming begins, strange things start to happen to the cast and crew. Equipment goes missing, and one of the actresses is attacked while taking a shower. When they investigate the farmhouse, they discover a bizarre collection of tools and torture devices. As they continue to film, the actors and actresses are systematically murdered by an unknown assailant.
As tensions mount and paranoia sets in, the surviving members of the cast try to unravel the mystery of the farmhouse and the identity of the killer. The film features graphic violence and images of torture, and was banned in several countries upon its release. X has since become a cult classic among horror fans.
