Rosie takes Big Breakfast host and Strictly star AJ Odudu to Moray in northern Scotland, to climb one of the highest mountains in Britain: Cairn Gorm. In this epic adventure, the pair tour the beautiful Scottish countryside, taking on a series of local challenges. They go head-to-head firing guns in a clay pigeon shooting competition, sample the area's famous whisky, test their strength rowing across a loch, try their hand at pottery, and in the hardest challenge of all, attempt to keep quiet on a retreat at Findhorn Ecovillage. At the end of their trip, will Rosie and AJ reach the summit of Cairn Gorm in one piece?
