Ten pairs of contestants arrive at the Fortune Hotel - an invitingly luxurious setting for a genuinely once-in-a-lifetime stay. Each room has an identical briefcase. Eight cases are empty. But inside one contains £250,000 cash, while another has the dreaded Early Checkout Card. Tension builds as each pair must try to uncover who has which case by playing compelling challenges, and as the “Whogotit” mystery ramps up, the couple with the cash must keep their case for eight days to win.
