A seasoned and highly skilled thief, Nick, is on the verge of retirement, aiming for one final heist to secure his future. Respected in the criminal underworld for his meticulous planning and execution, he now runs a legitimate business as a cover for his illegal activities. Despite his wish to leave the life of crime, he is tempted by an opportunity presented by his longtime friend and fence, Max, providing a chance for a major payday. The target is a priceless French scepter, which has recently arrived at the Montreal Customs House, a fortress-like repository. The job is risky but promises enough money to allow Nick to leave his criminal past behind for good.

Nick reluctantly teams up with Jack, a young, ambitious, and reckless thief introduced by Max. Jack has already initiated the groundwork for the heist by securing a job at the Customs House under a false identity and convincing Max of his thorough reconnaissance work. Nick is skeptical of Jack's loyalty and overconfidence and insists on taking the lead with a careful approach. As they plan the heist, a complex game of mentorship and manipulation unfolds. Nick needs to navigate not just the technical challenges of breaking into the impregnable Customs House, but also the unpredictability of working with a partner like Jack, whose motives and methods conflict with his own experience-informed caution.
