I remember the title is “INCINERATOR” , but I can’t find it on google.
It’s about the incinerator. The owner was an old man. He had a daughter (or granddaughter) . One day, he tried to rape that little girl in his room. She ran around in the room, fell and got unconscious. He thought she’s dead. So he threw her body into the incinerator with the help of a silly man. Though then they realized that the girl wasn’t dead, they still lockup her up and burned her alive. The silly man was always obsessed with the death of the little girl. He draw her picture being burned on the walls. Then that girl became a ghost and started to haunt them. The inspectors came and finally found out what had happened cause the girl showed them.
“Stuff Stephanie In The Incinerator”(1989)?
Just a wild guess by the title.
