A deadly virus is turning average people into killers. Caught in the middle of the growing power struggle of the DSA, Ben Riley and Morgan Dunleavy are dispatched to solve the case in Buffalo--Ben's hometown and the place he was framed for murder. Split between a need for answers to his past and an obligation to justice in the present, Ben winds up in the crosshairs of the madman behind the virus. A madman everyone thought was dead. Now Morgan must discover a cure to save Ben's life before it's too late. Loyalties are tested and sides are chosen in the penultimate chapter of the DSA's first season.
