Derren Brown: Incognito ()

We all make snap judgements about people, built on years of social conditioning and personal prejudice. But what happens when those prejudices are put to the test in the most unexpected circumstances? Ten strangers with wildly different backgrounds move into a mysterious institution for seven days. They all have one thing in common: an identity which leads people to make instant judgements about them. There might be a Soldier, a Spy, a Priest or a Porn Star. Each of the strangers think they have one aim: to learn the identity of the other players whilst keeping their own hidden.
