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. Every teenager thinks they're the only one not having sex. But for Alana, it may well be true. Skin A Cat follows Alana on an awkward sexual odyssey with a kaleidoscope of off-kilter characters: from getting her first period at nine years old and freaking out her frantic mother, to watching bad porn at a house party with her best friend's boyfriend, to a painful examination by an overly cheery gynaecologist - all in the pursuit of losing her virginity and finally becoming a woman, whatever that means. Show takes place in the Cavern space. Running time is approximately 85 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.
