Independent-spirited Constable Hamish Macbeth, Lochdubh's one-man police force, has his hands full as he searches among hostile gentry for the killer of a boorish house guest. When beautiful Priscilla Halburton-Smythe brings home her fiance, a famous playwright, all of Lochdubh clamors to meet the London celebrity—except for her long-time friend Hamish. But the fiance is pushed aside when one of the guests, a widely-hated hunter, is found shot to death. Everyone is quick to point out it could only be a tragic accident, but Hamish suspects otherwise.
