Unan1mous (2006)

Nine contestants from different walks of life are confined to live in a bunker without contact to the outside world. They must all decide unanimously which one among them should receive $1.5 million in cash. But the longer it takes to make the decision, the less money becomes available. Players who get eliminated from being eligible to win, will still be confined in the bunker and will vote on who will get the prize money.
