It's December 1967, and the town of Kinloch is cut off by heavy snow. With all roads closed, the only way to feed and water the townsfolk is for the fishing fleet to sail to Girvan for much needed supplies. But the skipper of the Girl Maggie, Sandy Hoynes, has a problem. First mate Hamish has, to everyone's astonishment, been chosen as Young Fisherman of the Year by a Glasgow newspaper. Marooned in the town and with one eye on a scoop, their reporter decides to join the fishing crew on their mercy mission. The thought of the publicity - and some remuneration - delights Hoynes. But Hamish hasn't told him the whole story. As the blizzards worsen, the crew of the Girl Maggie embark upon a trip like no other, encountering ghostly Vikings, gigantic crustaceans and a helpful seagull.

It's 1968, and the fishermen of Kinloch are preparing to celebrate the old New Year on the twelfth of January. The annual pilgrimage to the Auld Stones is a tradition that goes back beyond memory, and young Hamish, first mate on the Girl Maggie, is chuffed that he’s been invited to this exclusive gathering – usually reserved for the most senior members of Kinloch's fishing community. Meanwhile, it appears that the new owners of the Firdale Hotel are intent upon turning their customers teetotal, such is the exorbitant price they are charging for whisky. Wily skipper Sandy Hoynes comes up with a plan to deliver the spirit to the thirsty villagers at a price they can afford through his connections with a local still-man. But when the Revenue are tipped off, it looks as though Hoynes and Hamish’s mercy mission might run aground. Can the power of the Auld Stones come to their rescue, and is the reappearance of a face from Hoynes' past a sign for good or ill?
