A member of the public is given a second chance at life when mentalist Derren Brown makes him realize how important life is by tricking him into believing that a meteor has hit the earth and is now populated by zombies.
In the first programme, Derren sets up a fake pharmaceutical company which claims to have developed a drug named 'Rumyodin', with the ability to inhibit fear. In the second, Derren looks at the psychology of religious belief.
The Gathering was a live stage show performed in a secret location (hidden from the audience). The audience was hand picked by Brown and included psychologists, college students, celebrities, psychics, taxi drivers, and magicians.
