The "Blu Flu" has struck the Seattle Police force and a majority of the officers are on a unofficial strike, with the exception of a few, including Detective Lou Boldt, who is committed to the job. When a string of robberies and the brutal assault of a female cop rock the city, the pressure of isolation threatens Boldt's psyche and his marriage. With the help of psychologist Daphne Matthews and Sergeant John LaMoia, Boldt is able to make progress on both the assault and the robberies, but things soon spin out of control, and Bodt's refusal to drop the case puts his own life at risk.
