Nadir awakes from a living nightmare to discover Jose Alvarez is in custody and Paul Haskew was killed in the firefight. He returns home to discover Shaw made it out of the bust in one piece, but both break down over the death of Harman. With Alvarez keeping quiet, Nadir thinks he's in the clear, until he hears a body was found in the water after the raid; has Harman been found? Alvarez hints at what Nadir has done, but the comment about betrayal makes Heaton and Meadows send Nadir into a safehouse. Meanwhile, Keane and Hardy investigate a burglary and discover that the homeowners were gassed with Nitrous Oxide before being ransacked. Their prime suspect is their former nanny, fired for having an affair with the husband, but his constant arguing with his wife impedes Keane and Hardy's attempts to get to the bottom of the case.
