Locked in his cell, Leonardo tries to put the puzzle pieces together and wonders which one of his team members betrayed him. Perhaps his long-time friend Ghigo, the alarm expert? Or Sandra, the lock-picking prodigy? Could it even be Alberto, his hacker stepbrother?

Being romantically involved with a thief isn't easy. Anna, Leonardo's wife, is well aware of this as she finds herself cornered by Mertens. Judith Dewitt, the director of the Diamond Center, also comes to regret her involvement with Leo when she finds herself in the crosshairs of the investigation. Meanwhile, a mysterious man keeps a close eye on Leonardo.
