Lucie sur Seine.

Louis works for a dry cleaner in the Parisian suburbs. He lives in a council flat with his wife, Chantal, who works as a cashier in a local supermarket. Their relationship is tumultuous and lackluster; Louis longs to escape his humdrum existence. He wants to find a truck to drive to Lebanon. To carry out his plan, he commits a robbery at the supermarket where his wife Chantal works. His plan goes wrong when he fatally wounds a store employee and a security guard. He manages to leave the supermarket unharmed, his loot in his pockets. However, one person witnessed the gruesome scene: Lucie, another cashier. Why does this woman, who seems to have all the evidence to incriminate him, remain silent? Louis is determined to get to know Lucie to better understand the intentions of this mysterious man.
