When a police constable, Nick Bentley, is shot by drug dealers while on foot patrol it seems like a pretty straightforward case. Brooks and Devlin eventually locate a witness who identifies one of the parties to the drug transaction and he finally tells the police what really happened. The witness also tells them something else: she saw another police constable standing in the shadows while the injured policeman was calling for help. The dead man's partner, PC Ray Griffin, claims to have been several blocks away when his partner was shot and lay bleeding to death but Brooks and Devlin find an anomaly in his formal statement and they decide to investigate. What they learn is that Bentley's fellow constables had recently learned of his sexual orientation and that his partner Griffin is the head of a Christian group of officers that rejects gays.
