In the UK, one in 150 people have some sort of facial disfigurement, ranging from birthmarks to misshapen skulls, burns to facial cancers.

In a follow-up to Celebrity Wheelchair Challenge and the award-winning Celebrity Blind Man's Buff - which brought serious issues surrounding disability and blindness to a wider public - Channel 4 challenges two celebrities to be made up with striking facial disfigurements. They then go 'undercover' for 48 hours as secret cameras record members of the public's reactions to them.

Actor Craig Charles and model Caprice are disguised with wigs and glasses as well as astonishing prosthetic make-up, and their experience at the hands of people in everyday life is captured on film.

Will they be treated normally, or become victims of prejudice, ignorance and revulsion? And what will the experience teach them about the people who go through life with facial disfigurements, and about themselves?

Their experiences are mixed with the testimonies of a number of people with facial disfigurements, who tell their stories and reveal what it takes for them to deal with people's reactions on an everyday basis.
