I remember watching this film as a kid about 20 years ago. I was really into zombie films at the time so I went to Blockbuster with my mother and rented this movie.
I don’t remember the title at all and what I remember of the movie may be slightly inaccurate. The movie was about a group of European girls (British or Irish) who were either zombies, vampires, or cannibals. They lived in an apartment where they kept dead bodies. I remember that they didn’t start out as zombies or whatever but they slowly transformed over what seemed to be weeks/months. I clearly remember a scene where one of the females went into a bathroom and looked into a mirror and then started cutting her arms and wrists. The scene was very graphic and lasted awhile. I also remember a male detective trying to find where these girls are and he eventually stumbles across where they live.
Unfortunately that is all I remember. I have spent many hours trying to find the name of this movie. If you could help me that would be awesome.
