In the crypt of the remote castle of the Aguilars lies the recently-deceased body of Maria. Her husband Antonio is a jealous bully, his mute brother Ignazio is in a wheelchair peeping on his caretaker Sol, a novice. Also present are Miria, the couple's virginal daughter, and Isidro, a factotum who fears Satan's power. A frequent visitor is Juan Suarez, a doctor who wants Miria in a sanatorium for a month. She doesn't want to go. Isidro tries to exorcize the castle's evil spirits. Bodies pile up. Is Miria's mother truly dead, and who is Satan's tool?
Unfortunately the movie Satan's Baby Doll is not yet available on HBO Max.
