Dog Day Afternoons (S03E14)

After a string of bank robberies involving thieves wearing Johnny Cash masks, Rush finds a link that may provide new information on the 2000 murder of a young bank teller who was killed during an almost identical robbery. However, when Rush's clues run out, the team must retrace each step of the 2000 case in order to find the killer, who is still at large. (Warner Bros. UK)
