Marcel is the station chief of Mulhouse Train Station in eastern France. His big heart was torn after a break up, but he heals when his animal good deeds come to fruition like saving a duck named Mona Lisa. However, Vincent, traveling to Zurich, blew up on Marcel when his train and another train were held so Marcel could save the duck! Polar opposite personalities, Marcel and Vincent feel an odd sense of longing for something more, but they have their own lives. So they part ways, Marcel with the duck, and Vincent to Zurich for a job. Vincent comes back through Mulhouse and forgets his bag on the train. He looks at the station and knows that Marcel is there, but he doesn't want to ask him for anything; his pride is in the way. He has no choice and ask for their help. Angry over delays, his impatience gets the better of him. He says you stop hundreds of people for a duck, but when a person needs something important, it's phone calls. The tables have turned. Vincent needs Marcel and Marcel is the only one who can stop the train to search it. Will he? Will their personalities clash over what's important in life and lead their hearts to speak instead of their mutual dislike for each other?
