When Sara comes under suspicion that she’s infected after her mother falls ill, the city’s sanitation leader (Peter Stormare) comes to seize them both and deliver them to the Q-Zone. Nico must race against the clock, enlist the aid of a wealthy couple that may hold key (Bradley Whitford and Demi Moore), and navigate martial law to save Sara before it’s too late. Rounding out the cast is Alexandra Daddario as a singer entangled in a messy and forbidden affair; Paul Walter Hauser as a disabled veteran whose best friend is a drone; and Craig Robinson as Nico’s boss.
