I remember a very long time ago seeing a scene in a movie where a guy is in a house with some kids, and he kills them. Don’t know if he is the father but I remember he drowns a girl in the toilet, and a boy tries to fight back with a bucket I think. The boy dies and someone else gets killed as well. He hangs them up on crosses in a shed/shack looking place and ends up putting himself on a cross as well. Help arrives only to see the bodies. That’s all I remember.
