Note: most scary scenes in this movie have suspenseful music leading up to them but there are a few shock scenes.
A man enters a house and sees a body on the bed with it's head destroyed (blood is seen but is obviously fake) The man then enters the kitchen and sees a woman dead with a knife in her back (pool of realistic blood is shown)
A young man hits his father in the head with a baseball bat killing him.
After that, the man stabs his mother with a kitchen knife in the back.
After all that, he grabs his sister, drags her by the hair (she screams) into the bathtub where he pours gasoline over her. He lights it. No gore is shown but the woman screams and you can hear her the woman thrash.
