A story of drug importation from the waters of the Atlantic into the west highland coast of Scotland. At sea and in darkness three fishermen are killed and their boat lost. The bodies and vessel are not recovered and crime is not suspected. Andrew Fleming, an experienced police officer, voluntarily transfers to the area and uncovers a drugs importation ring. Fleming's efforts are unsupported locally. Greed, mistrust and murder among the protagonists provides an opportunity, outside his normal ethics, to bring an end to their importation.
