We follow Jesse, an American traveling through Europe, and Céline, a French student, who meet by chance on a train to Vienna. Striking up a conversation, they feel an instant connection and decide to spend one night exploring the city together before Jesse’s flight the next morning. Over the course of their night, they share deep conversations about life, love, and their dreams, growing closer with every moment. Their connection feels magical, yet is tinged with the awareness of its fleeting nature. The film captures the beauty of a chance encounter and the bittersweet tension of time.

Nine years later, Jesse travels across Europe giving readings from a book he wrote about the night he spent in Vienna with Celine. After his reading in Paris, Celine finds him, and they spend part of the day together before Jesse has to again leave for a flight. They are both in relationships now, and Jesse has a son, but as their strong feelings for each other start to return, both confess a longing for more.

It has been nine years since we last met Jesse and Celine, the French-American couple who once met on a train in Vienna. They now live in Paris with twin daughters but have spent a summer in Greece at the invitation of an author colleague of Jesse’s. When the vacation is over and Jesse must send his teenage son off to the States, he begins to question his life decisions, and his relationship with Celine is at risk.
