In the northern Scottish town of Lochdubh, PC Macbeth likes the idea of a trouble free life, but somehow trouble always finds him... As the local police constable, he likes fishing, walking in the hills and can see himself remaining a Highland constable for the rest of his days. Macbeth only has two problems. One is crime. The other is promotion. The latter of which he definitely doesn't want, as it would mean moving away from his beloved Lochdubh.
