Saturdays, now at 10 p.m.
A motley crew of retired police officers re-opens troublesome cases that were never laid to rest. From the discovery of a new motive in the killing of a college lecturer, to the tracing of a missing child, the team finds a way through the detail that eluded the original officers. But they are finding a surprising incidence of cover-up and conspiracy in their new investigations. Are their superiors about to close rranks? Or is someone feeding them particular files? Either way, the suspicion that they are being manipulated is high — and the team is determined to get to the bottom of it. These old dogs won’t roll over too easily.
