During a family meal, Joséphine's sister Diane announces her engagement, igniting Joséphine's insecurity about being single. Feeling pressure to seem successful in love, she fabricates a plan to marry a Brazilian surgeon named Marcelo. Her lie sets off a chain of life-changing deceptions that will ripple through her circle.

Joséphine expands the deception by claiming she is engaged to Marcelo and will move to Brazil with him. The lie becomes an obsession as she rehearses interactions and keeps up appearances for everyone around her. The fantasy begins to dictate her choices and travel plans.

Just before the plane departure to Brazil, Joséphine experiences a panic attack and is rushed to the hospital. Her friends remain unaware of the crisis, and her luggage disappears in the confusion. The incident exposes how fragile her fabrications are.

To avoid exposure, Joséphine hides in the apartment temporarily loaned to her by Chloe and Gilles. She continues the deception, and despite finding him tedious, she slowly starts to develop real feelings for Gilles. The living arrangement sets the stage for a complicated romance.

Joséphine's bag is returned to the apartment, revealing her true situation. Gilles calls her friends and confronts Joséphine about the lies. The confrontation cracks her carefully maintained facade.

To deflect the confrontation, Joséphine pretends that Marcelo died, crying fake tears to win Gilles' sympathy. Gilles and her friends see through the ruse and refuse to believe her tale. The deception collapses under the weight of her lies.

Joséphine finally admits her true feelings for Gilles. He refuses to forgive the deception, and he leaves, signaling a painful impasse for their budding relationship. The moment marks a turning point toward either reconciliation or permanent separation.

When Gilles arrives, he finds Julien, Joséphine's ex, staying at the apartment, leading to a dangerous misunderstanding. Gilles leaves convinced that Joséphine and Julien are involved. The misunderstanding complicates the possibility of immediate reconciliation.

Joséphine learns of Gilles' visit and rushes to find him to prove her love. She pursues him through the city, insisting that her feelings are real. The pursuit culminates in a moment of renewed emotional connection.
