I saw a movie about 4 years ago where there were two girls one of them I believe was a stripper. either way the second girl was being cheated on by the boyfriendand the friend girl number one ended up killing him,with what she states as a makeshift Shiv.
she pretty much spent the rest of the movie trying to dismantle the body using kitchen items throwing them in plastic bags etc. I believe another person was killed as well during that time I want to say it’s the landlord who comes in to complain about the noise that she is making. Help
