Heavy Heffers

The closing crew of Heavy Heffers double-check every night. So why is it that every morning the restaurant is trashed and there is no sign of the person who did it. They decide to find out on their own by bringing an Ouija board to the restaurant and contacting the culprit. What could go wrong with talking to the dead?
The manager Lizzy takes the questions too far and she finds herself in a not so pleasant situation. Her friend Alisha is her only hope to expel the ghost that has now taken residence in her body.
