Satan's Slave is a horror film released in 1976, directed by Norman J. Warren. The movie starts with Catherine (Candace Glendenning), a young girl who returns home with her parents from a vacation. However, on the way back, her parents are killed in a car accident, and Catherine is the only survivor.
She is taken in by her uncle, Alexander Yorke (Michael Gough), a wealthy and powerful man who is involved in a satanic cult. Her cousin Stephen (Martin Potter) is also a member, and they both take a liking to Catherine. However, it soon becomes clear that they have darker intentions for her, and she becomes caught up in their evil practices.
Catherine hears strange noises and sees strange visions, including images of her dead mother. She confides in her boyfriend Mark (Barry Stanton), but he is unable to help her and is also drawn into the cult's dangerous web.
As Catherine begins to uncover the truth about her uncle and cousin, she realizes that no one can be trusted. Even people she thought were dead start to reappear and haunt her, including her parents. The cult becomes more and more violent, and Catherine must fight for her life as she tries to escape and expose them.
The film has since gained a cult following due to its compelling storyline and intense horror elements. It is also notable for its shock ending, which leaves viewers questioning what they have just witnessed.
