March 2020. Véra makes a quick trip to Paris to feed a friend’s fish and water her plants while she’s hospitalized with a mild case of Covid. France is already abuzz with rumors of the spreading virus. But instead of hopping on a train back to Montpellier, as planned, she impulsively lies to her fiancé and says all trains have been canceled and she’s stuck in Paris… just as everyone else is hightailing it out of the city and the entire country goes into lockdown. So Véra holes up in her friend’s apartment, relieved to have a bit of quiet time to herself. Then she crosses paths with Sam — a chance meeting that changes her life.
Jonas, a 40 something Parisian, is still desperately in love with his ex-girlfriend Léa. When he knocks on her door to confess his feelings and she turns him down, he ends up at the café downstairs. Inspiration strikes and he sits down to write her a long love letter, dodging everything he was supposed to do that day. What begins as a last attempt to get her back surprisingly turns into a vivid musing on the state of his life. Over the course of a day, helped by a wisecracking bartender and an array of patrons from the neighborhood, Jonas has to face his past relationships, his uncertain future and, most of all, himself.
