Stand-up comic Rhod Gilbert tries out some proper jobs. This time he attempts to be a mother. He's put in charge of seven kids for a day when he takes over the running of a very large south Wales family. They may be smaller than his usual audience, but they are a lot tougher.

This time he takes part in one of the British Army's toughest training exercises in the Brecon Beacons. Will Rhod lose his sense of humour as he joins a crack task force in the deepest Welsh winter, or will it be a case of Who Dares Grins?
