During a volatile period in Edinburgh, Detective Tom is called to the scene of a shooting, a rare crime in the UK. The victim is a low-level criminal, and police fear the killing could signal the beginning of a gang war.

Investigators put pressure on local criminal networks, but the effort produces no new leads. With the case stalled, Tom changes course and takes a closer look at the people who witnessed the shooting.

What they reveal sends the investigation in a direction Tom never expected.
