It's My Party and I'll Die If I Want to
Sara's friends are throwing her a surprise birthday party, which also happens to fall on Halloween night. Sara is a huge horror fan and is also a martial arts bad ass. Her friends are setting the party up in the town's haunted house to help add to the creepiness of the whole thing. In the 1930's the town's venture capitalist went insane, locked his whole family inside and painted over the windows. After no one in town heard from them for a month or so, the sheriff goes in and discovers the whole family chopped up and the body parts placed in different piles throughout the house, all the left arms in one room, right arms in another and so on. The evil in the house woken up, possesses one of the kids who after a pretty gory transformation sequence, turns into a creature who rips the other kids apart. Sara must use her knowledge of horror movies and her martial art skills to get out alive while also paying the bastard of a creature back for tearing apart her peers.
