Dont mess with Bloody Mary

When Ash is left alone with her annoying older brother Mitch, the only option is that she calls her friends over for a sleepover. For the girls the evening started out like any other, just a group of friends hanging out and having fun. But when Mitch puts forwards an idea to do the Bloody Mary ritual at night, they all decide to go with it. What could possibly go wrong? It WAS only a stupid made up legend... right?
