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. The work of one of South America’s greatest artists, Pedro and the Captain by Mario Benedetti, has not been seen on the London stage for 30 years. Set in an interrogation room the play follows the confrontation of two human beings pushed to their limits and sees Pedro, fighting to retain his humanity in the face of an oppressive regime. This psychological battlefield offers up an universal reflection on states of oppression and dehumanization wherever they are found – war zones, refugee camps, boardrooms or bedrooms. Show takes place in the Crescent space. Running time is approximately 75 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.
