Creegan and Taylor investigate a serial killer who is sending reports of each of his murders to a local journalist, David Laney. When Rivers tails the prime suspect to a shack in the woods, his hesitation results in the death of another victim. However, with the killer in custody, Creegan is surprised to receive another message stating another murder is about to happen. The search of a warehouse yields another body, that of a local MP.

Creegan realises that Laney may have been the killer all along, and puts surveillance on him. However, when he slips out of sight, he confronts an innocent café owner who is later found dead, with her throat having been cut. Laney then kidnaps Taylor and takes her back to the shack in the woods. Creegan and Rivers arrive to find a hostage situation, but the guilt over his hesitation the first time leads Rivers to jump in and shoot Laney dead.
