Jimmy "The Tulip" Tudeski is a notorious mob hitman turned FBI informant living under an
assumed identity in a quiet suburban cul-de-sac in Montreal. His mundane new life is upended by the arrival of his unassuming, perpetually stressed dentist neighbor, Nicholas "Oz" Oseransky. Oz is trapped in a suffocating marriage to Sophie, a bitter woman whose mother despises him, and he is burdened by immense debts he inherited from his late, deeply corrupt father-in-law.When Oz recognizes Jimmy as the infamous Chicago mobster, Sophie immediately seizes an opportunity. Desperate to escape her miserable life and cash in on a multi-million dollar payout, she coerces Oz into traveling to Chicago to betray Jimmy to Janni Gogolak, the ruthless Hungarian crime boss who has been hunting Jimmy for years. Sophie’s ultimate motive is to split the reward money and have Jimmy eliminated.Upon arriving in Chicago, Oz’s inherent decency and terror at the prospect of murder prevent him from following through with a straight betrayal. Instead, torn between self-preservation and an unexpected, strange camaraderie with the charismatic hitman, Oz ends up warning Jimmy. Meanwhile, complications multiply rapidly with the arrival of Jimmy’s beautiful, estranged wife, Cynthia, who is also hiding from Janni. Oz finds himself hopelessly infatuated with Cynthia, offering her comfort and protection amidst the escalating chaos.Back in
the neighborhood, the web of deception tightens. Janni Gogolak arrives in Canada, accompanied by his sadistic enforcer, Ypsilon, intending to settle old scores. Simultaneously, the ruthless FBI agent sent to handle Jimmy turns out to be corrupt, conspiring with Sophie and Janni to secure the insurance money tied to Oz and Cynthia.As the factions collide, shifting loyalties and elaborate double-crosses take center stage. Jimmy reveals that he is several steps ahead of everyone, orchestrating a brilliant master plan to fake deaths, outsmart the mob, and secure his and Cynthia's futures. Oz, once a passive victim of circumstance, finally learns to assert himself, shedding his submissive demeanor and aiding Jimmy in executing the final scheme. In the chaotic aftermath, Janni and the corrupt FBI agents are neutralized, the insurance fraud succeeds, and Oz walks away a free and wealthy man. He leaves behind his toxic marriage and embarks on a thrilling new life with Cynthia, realizing that rubbing shoulders with a contract killer was the best thing that ever happened to his otherwise dull existence.
