Ant Middleton presents the final stage of the celebrity training challenge to raise money for Stand Up To Cancer. The mental strain of previous episode's interrogation test leads to a series of drop-outs, but for those who remain, a far more daunting task has been prepared to test their physical strength to the limit. Ant and his directing staff take the celebrities to the El Morado glacier, which stands 3000 metres above sea level, where they will face the final assignment to determine if they have what it takes to pass the course. Last in the series.
