Twelve contestants, who have never met are challenged to stay in a house, cut off from any contact with the outside world for 85 days. There is a cash prize of $250,000 for the winner. The contestants are free to leave at any time, but if they do, they walk away empty-handed. Once a week the contestants nominate three members of the group for eviction, with viewers making the final decision, by way of a phone-in, of who will leave the house. Conditions inside the house are basic, but occupants earn money to supplement their rations if they all successfully complete weekly assignments, designed to test their team spirit. Over the weeks the numbers will be whittled away until eventually, one contestant will emerge victorious. In the meantime, the residents of the BIG BROTHER house have no idea of what the public thinks of them or what impact they are having on the world.
