Mystery of the Old House(1987)

Mystery of the Old House is a supernatural thriller that follows six teenagers who accidentally awaken a vengeful ghost haunting an old mansion. The spirit seeks retribution against Susi's father, who years earlier committed a brutal crime against the ghost's family. As the haunting intensifies, the ghost—trapped in the form of a curious child—begins to terrorize the group. A dark bargain emerges when the spirit agrees to cease its rampage, but the cost proves far more sinister than anyone anticipated. The teenagers must uncover the truth behind the ghost's tragic past and find a way to break the cycle of violence before the supernatural revenge consumes them all.
