Walker's operation goes pear shaped when the team's prime suspect turns out to being nothing more than a bag snatcher. However, when one of the former victims is contacted by her attacker, the team discover that the culprit is a driver from Stamp's cab firm. As Stamp attempts to do some digging, the attacker contacts his victim again, and Stamp is able to identify him. However, forensic evidence only links the suspect to one of the attacks. Meanwhile, Fletcher and Keane deal with a teenage girl who has entered an abusive relationship with an older boy in an attempt to gain access to alcohol, and Sim discovers that she has been accepted as the new sergeant for the Kidnap Squad.
