When a deal goes wrong, and the team are left with a priceless diamond, they are forced to take on their most dangerous mark to date. Their initial good fortune turns out be more of a curse when they discover ruthless millionaire Toby Baxter is prepared to track it down at any cost, sending in notorious tracer Pinky Byrne to hunt down Mickey and the crew. Mickey thinks they can keep the necklace if Emma is willing to trick Baxter, but has Emma agreed to the risky plan for the wrong reasons? And if so, will Baxter see through her lies? The answers to both of those question would, of course, be a resounding 'yes'.
