It's 1967. Veteran fisherman Sandy Hoynes and first mate Hamish are stuck in port due to heavy snow. With all roads blocked, the Kinloch community turn to their fishing fleet to make for the Ayrshire coast in search of vital supplies. At first, Sandy is reluctant, but when a reporter from the Fisherman's Quarterly offers to accompany the brave mariners on their mercy mission, Sandy changes his mind. 'We'll be legends of the west coast fleet!' he tells his dubious first mate. But when reporter Jo Baird arrives on the quayside at Kinloch, there is a serious problem. The crew of the Girl Maggie face snowstorms, superstition and unexpected cargo as they set off to save the hungry folk of Kinloch. Have they bitten off more than they can chew?
