Lesley Joseph, Don Warrington, Melvyn Hayes, Nick Heyward and Cleo Rocos visit waterfalls in the Brecon Beacons, paddle on unspoilt beaches on the Gower peninsula, and make a splash in the waters of the stunning Pembrokeshire coast, all while the cosy living conditions bring this company of celebrity strangers closer.

The famous five head for Scotland's highlands and islands, where Lesley has to face her fear of heights, Cleo gets an adrenalin rush and Don and Nick experience the magic of the Glenfinnan viaduct and the Harry Potter express.
