Grégory Van Huffel, known as Greg, runs a discreet agency called Alibi.com, a service that provides people with alibis to keep their romantic secrets hidden from their partners. As the business grows, Greg finds himself falling for a lawyer who champions total honesty in relationships, creating an undeniable tension between his world of carefully crafted lies and the truth she values.
He meets Florence Martin by chance, and the spark between them grows even as his professional life remains a tightly guarded secret. Florence believes that honesty is the foundation of trust, a belief that clashes with Greg’s line of work. To win her heart, he makes a risky choice: he conceals his real job and tells her he works as a steward, hoping the truth won’t derail what could be a meaningful connection.
Their romance faces a new test during a trip to their parents’ country house. There, Greg discovers that Gérard Martin is one of Alibi.com’s clients, a realization that complicates his feelings and duties. Meanwhile, Florence’s mother, Marlène Martin, believes her husband is away on a business trip, adding another layer of misunderstanding to the family dynamics. In Cannes, Gérard meets with Cynthia Bellini in a hotel, a thread that intertwines with the couple’s own misadventures. As fate would have it, Florence’s mother ends up in the same hotel during the same period, bringing all the players into a tightly wound knot of secrecy.
An emergency pulls Gérard into Greg’s orbit, forcing Greg to respond when Gérard calls for help. To provide the needed alibi, Greg must keep Florence in the dark about his real life, even telling her that he is traveling to Tanzania. The tension escalates as Greg is torn between protecting his client, keeping his cover, and preserving the fragile trust he’s begun to build with Florence. Under no circumstances should he run into her, a rule that becomes nearly impossible to observe as all the threads converge.
As the weekend unfolds, the delicate balance between deception and desire frays. The film unfolds like a web of near-misses and awkward encounters, where every lie ripples outward and threatens to shatter the relationships at its center. In a climactic turn, Gérard and Greg confront the consequences of their choices and confront a reckoning with the truth they have been dodging.
In the end, both Gérard Martin and Greg confront their own missteps and seek a path toward redemption, while Cynthia makes a bold, public move by publishing Alibi.com’s customer list on the Internet. The revelation exposes the limits of keeping secrets and the price of deception, leaving the central relationships to reckon with the fallout. The story closes with a note on accountability and the messy, human costs of trying to control the truth.
Overall, the movie blends light humor with a domestic drama about trust, honesty, and the consequences of living behind a carefully constructed alibi. It invites the audience to consider how far someone should go to protect a relationship and what happens when the fear of the truth becomes a game that spirals beyond anyone’s control.
