Graham Merrill is working in a dead-end job in London when he adopts an otter, Mij, as a pet. He soon realizes that his small apartment is not the ideal place to keep an otter. Figuring that it's time to work on the book he always intended to write, he quits and moves to a small cottage in an isolated village on the west coast of Scotland. The change makes for some great adventures with Mij and causes Graham to meet Mary MacKenzie, the beautiful town doctor.
