Ten celebrities have arrived to take part in the most gruelling - and lucrative - reality survival show ever devised: two weeks completely alone on a remote Scottish island, in the depths of winter.
With a production team that seems incapable of keeping them safe, a gathering storm and the unrelenting gaze of hidden cameras, the contestants are stretched to the limit as they try and outshine their fellow competitors and hide their darkest secrets.
But when a contestant winds up dead, it soon becomes clear that the players are not just fighting for the prize, but for their lives.
