When firefighters respond to a suspected meth explosion at a trailer park, they discover a man’s body in a neighboring trailer, unburned but with terrible head wounds. The meth cooker lies in critical condition, and undercover narcotics officer Stephen Holder feels a kinship with the child the man leaves behind.

Then another man’s body is discovered in a shipping container at the Port of Seattle, shot execution-style. For Homicide Detective Sarah Linden, two cases soon become one, and she must unravel a complex web of addiction, greed, and betrayal to reveal a killer.
