Gary is determined to bring his former lover to justice for her part in the money laundering scam, and when Phil and Ken's undercover operation goes awry, Gary realises the pressure is entirely on his shoulders to get a result. A surprise comes when Jo uses a neat trick to cover up Gary's part in the scam. Meanwhile, June and Roger are called to a disturbance at a train station, where a group of rowdy schoolgirls have been accused of fare dodging. As a scuffle ensues, Amber jumps to Leela's defence when one of the girls tries to attack her with a broken bottle. Roger, however, comes off worse when one of the girls accuses him of sexually assaulting her during the skirmish.
