What if the person you trusted the most suddenly became a stranger, who desperately wanted you dead? And if an hour later, they were back to normal? Detective Jack Arnette was a respected cop, before a hostage situation went horribly wrong. Victor Slade is a meditating, hedonistic cop-killer. When Victor makes a pickup at the Seattle docks, Jack sees a chance for redemption. A simple arrest. Respect regained. But events spin out of control when Jack and Victor are quarantined with the dock workers and a virus that can make anyone go temporarily homicidal. Trapped by a SWAT team with orders to shoot anyone who leaves the building, Jack must deal with a cop-killer who has little to lose, and a group of innocents who could become just as dangerous. Who would you trust when anyone could become a killer?
