BBC Radio 1 DJ Greg James is to host a new Channel 4 reality series from the makers of hit series The Traitors.The game show, titled Rise And Fall, will see 16 members of the public, from all walks of life and ages, begin the game as equals but soon find themselves either in a position of power as a “ruler” or as part of the powerless as a “grafter”.The set-up will reflect real-life power dynamics as the grafters survive in basic conditions in a basement while the rulers live in a penthouse. Greg will oversee the action as the grafters work to complete a series of physically demanding games and challenges to build a cash prize fund only the rulers can win. The rulers must encourage the grafters to work harder, but if they push too hard they might find themselves toppled from power.
