In the main plot, Derren's "trick"-victim is Steven, whom he gives a
taste of temporary lunacy.
The subject is firstly kidnapped in a London taxi cab and then becomes a street madman. Side plots include Derren showing to Martin Freeman the power of new
age crystals and a group of bankers guessing the number of pieces of
candy in a jar and coming up with a numerical equivalent.
The subject is put into a trance and wakes up at the scene of a
staged road traffic accident in which she sees herself dead in her car.
She is unable to move and the 'rescue personnel' do not respond to her
presence. Prior to its broadcast, this episode was criticised in the Daily Mail newspaper for trivialising the issue of road deaths and potentially harming the subject psychologically.
Trick or treat is a British television show hosted by Derren Brown. The focus of the show is on one person selected from a pool of
volunteers who responded to adverts in the national press to take part
in the show. The experience the volunteer receives is decided by which
card they choose. If they choose the card that says 'Trick' they
receive a bad experience and if they choose the card that says 'Treat'
they receive a good experience.
Trick or Treat Season 2 - Episode 1: Quiz
The subject is taught a technique of speed learning, and spends a week
scanning hundreds of books in preparation for a Night of the Champions
pub quiz, in which he enters as the only solo participant and comes
second only to two teams who tied for first place.
The subject is shown a kitten in a metal cage and told that it will be
electrocuted if she presses a button. The subject would win £500 if she
stays in the room for five minutes without killing the kitten. Derren's
forces her to press the button at the last second. However, she finds
the cat is still alive and thus wins the £500. The treat was that the
subject would think back to the moment if she was ever being negative
in future, and would then become a more positive person.
The subject, guest star David Tennant,
appears to have the ability to time travel. He is taken back to the
early 1930s and gives out facts, which appear in a newspaper from that
date. He then predicts what a member of the public will draw on a card,
twenty minutes beforehand. Finally, he performs automatic writing, predicting two news items which would appear three days later in The Guardian
newspaper. It was mentioned in the episode that Tennant had applied to
the programme in the same way any ordinary member of the public would.
