Derren Brown - Trick or Treat

Derren Brown persuades members of the public to sign a Faustian pact with him and participate in a macabre game of `Trick or Treat'. First up is Richard who is put to sleep in a photo booth in London only to awake again in Marrakech. Also, Derren attempts to plant a word in the brain of an unsuspecting American, and back in the UK, he plays a game of fate with `The League of Gentlemen'.

Derren's tricks and treats includes an IT consultant who has his otherwise ordered world turned upside down by being given the experience of a split personality. Also, Derren invites `Guardian' art critic Adrian Searle to slash through a priceless work of art by BritArt `enfants terribles' Jake and Dinos Chapman, and goes shopping in New York with a wallet full of blank pieces of paper.

North London pensioner Anne is in for a treat as Derren teaches her to play Texas Hold 'Em poker and enters her into a professional tournament. Plus, Derren becomes a living waxwork in Madame Tussauds in London and visits a Las Vegas nightclub where he makes a woman temporarily colour-blind.

Steve is shown the darker side of London life by being given an opportunity to live life as a `street' madman, Martin Freeman is shown the power that new-age crystals can hold, while in America, Derren predicts the behaviour of a large crowd of accountants.

Yshani, a young Sri-Lankan woman, selects a `Treat' card and is taught to play the piano to concert standard and performs a recital at Wigmore Hall after only two weeks of lessons with Derren. Derren also disguises himself as a waiter in New York, and attempts some psychic reading with his lunchtime customers, while actor Simon Callow falls under Derren's influence.

Psychologist Jules chooses a `Trick' card and finds herself witnessing her own death in a staged out-of-body experience. Plus, Derren travels to Queens in New York to see if he can tell when a group of second-hand car salesman are lying, and back in London, he tries to plant a single thought in the heads of a crowd in Covent Garden.
