Manson, now with MIT, is called to visit dying convict Vince Parker, who after admitting to an unsolved murder more than twenty years ago, accuses Meadows of framing him for a post office robbery as revenge for him escaping the murder charge. Manson, now forced to investigate his old boss, is teamed with DCI Frank Keane of the DPS, who is less than keen to see Meadows slip off the hook once again, after an incident at Stafford Row back in the '80s. Meanwhile, Meadows hooks up with his old DI, Dougie Price, in an attempt to clear his name. Parker's accomplice in the armed robbery then decides to back up his story, and then accuses Meadows and Payne of beating him to a pulp. (thetvdb.com)
