An amateur boxer trains hard to become a professional, but soon has tough choices to make when family life and a boxing career become hard to balance.

After being dumped by his girlfriend, Zack's big brother decides to throw him a house party in the derelict old retirement home he has been refurbishing. The building has a history; the previous owner believed the residents had become possessed by demons, so he locked all the doors and set the place on fire. During the party, Zack's friends start to fall victim to the same curse.
