Maze Master Richard Ayoade guides former footballer Dennis Wise, DJ Roman Kemp, Made in Chelsea's Binky Felstead, Happy Mondays maraca shaker Bez and former model Katie Price through the Aztec, Medieval, Industrial and Futuristic zones. In each one, the contestants must conquer physical, skill, mystery and mental challenges in a bid to win crystals to swap for time inside the iconic Crystal Dome. Along the way, Katie sizes up the Medieval Zone as a potential wedding venue and Bez becomes mesmerised by the flying tokens in the Dome.
