Don't Go in the House (1979)

Donny works in a factory which has incinerators, but his co-workers are not aware that he is obsessed with fire and that he is a mentally disturbed man because as a child, his mother punished him with burning to remove the evil out of him. After his mother's death, Donny gets excited as he is finally freed from her and starts playing loud music and lights a cigarette in the house, but his excitement fades away when he begins to hear a voice in the house that seems to be his mother's. The voices and delusions about his mother still being alive makes Donny go crazy and he soon starts kidnapping women and later burns them alive.
