The Unexpected Night

One night, Ella, Amber, and Robin decide to throw a huge Halloween party at Amber's parent's house. On the way, Amber and Ella stumble across two guys, they see as perfect. They decide to go somewhere quiet upstairs and end up getting locked in and having the lights on and off. Will they make it out alive?
