A group of well known personalities live together in a specially constructed camp site in a jungle, isolated from the outside world, and not aware of outside events. The contestants compete for $100,000 to be donated to a charity of their choosing, in addition to being personally reimbursed for their participation. While in the jungle, some of the contestants (generally voted by the viewing public) compete in challenges for food and luxuries for the camp. These challenges often involve local wildlife, and are meant to take the contestants out of their comfort zone. Each week one or more of the contestants are evicted from the jungle, based on viewer votes. They can quit at any time, with a reduction in reimbursement, by uttering "I'm a celebrity; get me out of here".
