DC Webb investigates a robbery at a clothing factory, and his investigations lead him to Norman Klein, Nick's uncle. The link between the latest robbery and a previous one is revealed to be Jerry Klein who assessed security at both places. When Jerry is found badly beaten, Nick decides he must tell the police about his cousin's possible involvement, which results in DI Cullen catching the gang on their third job.
