In Miami, when a young father-to-be is gunned down in broad daylight, Sgt. Eunice Cooper and Detective Ervens Ford are sure they know who did it. But when their primary suspect claims he was at home when the shooting occurred, and has the record from his GPS ankle bracelet to prove it, they must work against the odds to catch their killer. In Phoenix, Detectives Steve Orona and Jeremy Rosenthal respond to a call of a foul odor coming from an apartment. When they arrive at the scene their worst fears are realized. The body of a woman, wrapped in a blanket, is decomposing on the floor of the bathroom. The detectives are now in a race against time to try and find the killer. They chase their suspect to Mexico, hoping to find him before he disappears.
