I believe I was about 9 when I watched this but here goes

the only parts I can remember is there was a couple living in a house with 2 children that lived inside

a black man and his nephew went knocked on the door and then the man was killed, the remains were a bit disgusting

another thing I can remember is the daughter had blood on her dress and the woman made her bath in boiling hot water, not too sure if the nephew dies or not
