New Tricks - Series 1 (DVD)

A motley crew of retired police officers are assigned to re-open troublesome cases that were never laid to rest. From the discovery of a new motive in the killing of a college lecturer to 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 ranks? 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.
