In the secluded western coast of Scotland, a drug dealer betrays and murders a drug trafficker who supplies him with narcotics. The dealer is apprehended and discovers that a pair of unidentified locals witnessed the crime. Facing a life sentence, he decides to hire a hitman to eliminate any possible witnesses. Outside a rural police station, the hitman starts a stopwatch, dashes across the road, jumps into his car, and speeds away with a screech. He races through the desolate countryside until he reaches the isolated, single-street village of Bartoun. He checks his stopwatch, which shows 28 minutes and 36 seconds. He notices a poster announcing a fair in the neighboring village, advising Bartoun’s residents to gather on the main street at noon for transportation. As the villagers begin to assemble the following day, the hitman approaches and starts shooting, aware that he has 28 minutes and 36 seconds before the police arrive.
