London's biggest arts festival is returning: make your way underground for six weeks of creativity, innovation and chaos at Vault Festival. With more than 100 different shows spread across eight incredible venues, you're not going to find anything else like it above or below ground any time soon. For centuries people have used the Ouija board to help quench their thirst of the unknown: "Is anybody there?" "What happens when we die?" "Have you seen my pet hamster?" When Leo returns home to find his flatmates dabbling in the dark arts, it's not long before the night takes a sinister turn. Show takes place in the Crescent space. Running time is approximately 60 minutes. The venue entrance is in a graffiti tunnel under Waterloo and can be a bit tricky to find, so give yourself good time to get there.
