Happy Birthday to Me
is a Slasher Movie
Set in the prestigious Crawford Academy, the film centers around Virginia who suffered a traumatic accident on her birthday during her childhood. As another birthday is coming near, her buried memories of that fateful day have started returning little by little. But she also tends to have blackouts during these events. And some people tend to coincidentally disappear too, especially
those close to her...
These are jolly good examples:
- Twist Ending: The film became a notable slasher film mainly for its Mind Screw ending; the killer is Virginia's best friend Ann, who is also her bastard half-sister who has been systematically drugging her and wearing a latex mask that makes her Virginia's exact double.
