Heartbreaker

Alex, Mélanie, and Marc run a boutique operation that ends relationships for clients who believe the woman is unhappy. They devise elaborate, tailored deceptions to persuade the target that love has changed. After each ruse, Alex tells the woman she has come alive again, even though the relationship ends.

A wealthy florist and gangster hires the trio to prevent his daughter Juliette from marrying Jonathan. They are given ten days to derail the wedding, a countdown that tightens as time passes. Alex initially declines the job but pressures from a loan shark push him to accept.

The trio researches Juliette and Jonathan and discovers they are genuinely in love and perfectly matched. The usual flaws they exploit are absent, making the mission seem almost impossible. The stakes rise as the deadline approaches.

Juliette travels to Monte Carlo for wedding preparations and Alex poses as her bodyguard to gain constant access. The trio secretly bugs her hotel room and secures an adjoining room to monitor her. This arrangement lets them observe her life up close.

While on the job, Alex learns Juliette's tastes—Dirty Dancing, Roquefort cheese, and George Michael—and feigns enthusiasm to win her trust. He mimics these interests to create a convincing connection. The growing chemistry complicates his mission.

Jonathan arrives earlier than expected, cutting into Alex's access to Juliette. The planned routine starts to fall apart as opportunities for manipulation shrink. Tension rises as real feelings threaten the ruse.

The night before the wedding, Juliette and Alex sneak out for a playful evening, recreating the final Dirty Dancing dance. Juliette admits her feelings, and Alex grapples with the conflict between love and deception. He decides to tell her she should get married, breaking his usual script.

The morning after, Marc drops Juliette's case file in front of her as they leave the hotel. She sees surveillance photos that reveal her father hired Alex to stop the wedding. The revelation reframes the mission and the relationships involved.

At the airport, Mélanie scolds Alex for abandoning real love for a hollow life, urging him to reconsider. He races toward the wedding to salvage something meaningful. The moment heightens the personal cost of the deception.

As they walk down the aisle, Juliette's father tells her that Jonathan is decent but she would be bored with him. He notes that Alex refused to take any payment for the contract. The revelation tests Juliette's resolve and sets up her choice.

Juliette defies the ceremony and runs to find Alex, who confesses the truth about his feelings and their past deception. They share a kiss, acknowledging a real connection beyond the ruse. The moment hints at a possible future together.

Back at the 'non-wedding', the loan shark is revealed to work for Juliette's father, adding a further twist. Sophie quietly flirts with Jonathan, complicating the post-ceremony situation. The trio's schemes shift toward a new, uncertain plan.

Mélanie and Marc attempt another ruse, but without Alex's charm their plan fails. The story ends with the trio facing a complicated balance of love, debt, and loyalty, suggesting the business will endure but under a different dynamic.
