Other members of the cast include actress Sharon Lloyd as a fake volunteer and magician Paul Andrews as Head of Experiments.
In this show, four volunteers are challenged to stay for 48 hours in a disused mental asylum and endure a series of mental challenges designed to test their courage.
A cast of actors and stuntmen are used to increase the realism of the challenges, while psychological tricks and illusions aim to convince the volunteers that they are really facing their worst fears.
When not performing a challenge, the volunteers are escorted to their cells by unknown masked men who never talk, to create an environment of stress and panic.
The volunteers are also allowed to leave the asylum at any time should they be unable to continue, but those that stay to the end are rewarded with the knowledge that they have faced their greatest fears.
