9 people enter "The Bunker", which is a building that the contestants stay in for a week.
Once they are in there, they will be there to fight for the £1,000,000 prize fund. But there is a catch - they must all agree on who gets it with tactics, gameplaying, scheming and some levels of bitchiness.
They will be given different tasks, which will give each other some more ideas as to whom should win or who is more worthy of it.
If the participants can't make a unanimous decision, then they will have to choose an outcast, so the person with the votes from the other contestants will then not be able to win the prize money, but will still remain the bunker and still has a say as to whom should win.

But, in my version, there will be some differences. They will be divides, splitting the bunker up to cause tension, the public can actual evicted a contestant permenantly, etc...
