This film follows a year on the exquisite west coast of Scotland, in the intimate company of a family of otters. Guided by their mother, the otter cubs survive the wildest storms of the Scottish winter, striving to overcome many challenges on their way to independence. The west coast is warmed by the Gulf Stream which is why dolphins and sharks, whales and puffins all come here to share it with the otters. Two years in the making, this film is packed with surprises and excitement and set in the most breathtaking scenery to be found anywhere in Britain.
