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 include 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 salesmen are lying, and back in London, he tries to plant a single thought in the heads of a crowd in Covent Garden.
