Richard Bacon follows members of the public who scientists believe could have extraordinary abilities they were never aware of. In the first episode, a 45-year-old nurse is identified through a series of scientific tests as a potentially gifted climber, and receives expert training from coach Martin Chester before tackling the Old Man of Stoer, a 200ft-high stack of sandstone off the coast of Sutherland in the Highlands - an ascent which is usually attempted only after years of training. Elsewhere, a 63-year-old retired woman discovers she has an advanced ability to detect lies, and travels to America for a two-day crash course in interrogation techniques with former FBI agents Jack Schaeffer and Joe Navarro.
