I saw it ages ago but I can't remember the name of it.
I remember only bits and pieces of it.
So this guy was really fucked up in the head and he and his girl/wife kept getting in fights and shit.
During one of their fights she runs into the bathroom and ends up finding a box with some other chicks finger in it with a ring on it.
After that he breaks into the bathroom and slowly shoves a rather large knife into her leg.
Later in the movie he wears a bunch of make-up type mask shit on his face and finds that girls old friend from back in the day.
Anyway he ends up fucking her then suffocating her with a plastic bag.
That's about as much as I remember of it.
