A little snail lives in a flock, on a rock by the docks, and longs to see the wider world. After writing an advert for a lift wanted around the world, a humpback whale arrives one night and offers to take her travelling. The pair see many sights along their way until one day the whale, confused by the noise of a group of racing speedboats, swims into a bay and is left beached by the retreating tide.
