Derren Brown - Trick or Treat

Derren ambushes Glen, a father of two, and persuades him to compete in a Night of the Champions pub quiz, where the top teams from all over London will be gathered. Can Derren turn him into a genius in only seven days?

Derren demonstrates the power of negative suggestion by taking 19-year-old Lauren on an emotional rollercoaster to see if, having been told NOT to, she can resist killing a kitten – which is in a metal box wired up to the mains electricity.

Actor David Tennant is ambushed by Derren whilst filming on location and agrees to undergo a series of experiments that have him experience the feeling of time-travel. Will 'Dr. Who' be able to regress back in time and witness an event from the thirties?

Agency worker Angela is surprised by Derren in total blackout in an office. Over the next few weeks, she is given a number of tasks to fulfill, both physical and mental, to ensure she is ready to face probably the most challenging experience of her life.

Derren attempts to transform IT worker Jason from a nervous doubter to a confident go-getter by teaching him a number of life-enhancing techniques that unlock the secrets of powerful confidence.

In this finale to the series, we experience the power of superstition when Derren executes one final twist on all the previous participants, including David Tennant, who have arrived for the end-of-series wrap party.
