Watch Sadisflix. Wadi Rum, known as the Valley of the Moon, is a vast landscape of sandstone walls in the desert of Jordan. Hoping to lure international climbers, two Israelis team up with a local Bedouin guide to establish a 1,800-foot route, eventually recruiting American climber Madaleine Sorkin to help achieve their dream. Valley of the Moon explores the importance of climbing as a way to cross cultural barriers, build friendships, and chase adventure in one of the most breathtaking regions on earth.
