Victor Maher (David Calder), a hard-nosed ex-fraud squad officer, is on Mickey's case. The only man to have nailed Albert Stroller, Maher has damming evidence on Danny Blue and is prepared to use it if he doesn't get what he wants. He demands that Mickey help him catch Sam Richards (Richard Harrington), a thief who is breaking into branches of the bank for which Maher works as head of security. Mickey is loath to even give Maher the time of day and tries every way possible to get out of helping him, but the cunning ex-copper is always one step ahead, leaving Mickey with no choice.
Mickey's team doesn't do bank jobs, so the gang is surprised when he fills them in on their next scam. Albert is more concerned about the risk Mickey is taking; Maher is proud of his conviction record and nothing would please him more than to be the one to nail Mickey "Bricks" Stone. Meanwhile, Stacie is charged with keeping Danny away from the action and, after a day of scamming an army of shopkeepers, including unashamed snob Paul (David Williams), they end up having a steamy game of strip poker. Later, against his better judgment, Albert ropes Sam in on the scam, just like any other con, promising to introduce him to Ash, posing as an alarms expert. However, once Sam explains the personal reasons behind his bank breaking, Mickey changes his allegiance and the team is out to wreak revenge on the increasingly smug Maher. But with CCTV, armed guards and only one entrance/exit, this bank job proves to be the hardest and riskiest scam yet for Mickey and his team.
