OK, it's not brand spanking new like the rest of tonight's offerings, but it's only the second episode so it's not too decrepit. In tonight's instalment, a bungled robbery leads to an innocent have-a-go hero being shot dead and a cab driver being taken hostage by the two thieves making a getaway from the crime scene. When the police capture one of the accused, Frank Donovan (Rob Jarvis), they are desperate to know the whereabouts of his hostage who has a potentially fatal medical condition. Realising he has a bargaining chip to play with, Donovan offers the team a deal he will tell them the location of the captive in return for immunity from prosecution. Tamzin Outhwaite (Hotel Babylon) guest stars as uncompromising lawyer Miriam Pescatore.
