Pairs of contestants receive a modest starting pot of seed money comprising £250. As soon as they receive the cash the clock starts ticking and their mission is clear - double the money within the next exhilarating few hours or face elimination from the game. The stakes get higher until one team ultimately wins a life-changing £20,000. Those taking part include father-and-son Dale and Harvey, competitive publicans Cath and Lynn, and best friends Radhika and Seema.
