A lonely boy living in the Scottish Highlands during the Second World War stumbles on a curiously large egg by the water's edge of the local loch. Astonishingly, it hatches into a cute baby sea monster and, although he tries his hardest to keep it concealed, the task is made almost impossible by the creature's alarming rate of growth. Children's fantasy adventure, based on the book by Dick King-Smith, with Alex Etel, Emily Watson and David Morrissey
