The film opens with the pretty doctor Regina sticking a gun in her mouth and pulling the trigger. We are then informed that she had "murdered and cannibalized at least 4 men, but had never been brought to trial."
Cut to a mental hospital where Regina is being treated by a psychiatrist, after surviving her attempted suicide. She insists that she is a monster who he must let die, while he insists she has schizophrenia.
The bulk of the film is then told through flashbacks that show us her courtship and eventual engagement to Ryan, an EMT. Ryan and Regina attend a karaoke party in which drugs are involved, and Regina has a bad reaction and is rushed off to hospital. Soon after recovering, she finds that she can no longer stomach normal food, except for raw pork.
Soon that is not enough and she finds that she can only subsist on human remains, so after work she steals those bags labelled "biowaste" out of the hospital garbage and brings them home to consume.
What follows is an increasingly ludicrous series of events that pretty much defies logic. Regina pours bags of human fat into a glass, and drinks it like a milkshake while her fiancée looks on, giggling. It doesn't even seem to phase him. She tries to eat him and he laughs, and tells her to hurry to work. They watch a documentary on ants and decide from that that she has a fungus in her brain.
None of this seems to make any sense to me but I went with it, waiting for something interesting to happen. Nothing really did. The two leads do a passable acting job but Regina's psychiatrist character is portrayed with some of the worst acting I have ever seen. The sound is horrible and the music sometimes is so loud that you can't hear what the characters are saying. All in all a big letdown, with a laughable ending.
