The North Berwick crew race out to try and save a windsurfer battling the seas as he and they fight the gale-force winds of Storm Dennis on the east coast of Scotland. In Carrybridge, on the banks of Lough Erne, Northern Ireland, the crew face two very different challenges: a man who’s become trapped under a digger on one of the lough’s islands and a cow that’s become stuck in the mud on the shoreline. And in Dorset, the Lymington crew race to the rescue of an elderly casualty whose yacht is caught on a lobster pot and is at risk of being overwhelmed by the stormy seas.
