In Paris, Mona Dessaint is authorized by the justice to leave the prison where she is incarcerated to work at a coffee shop at the Gare du Nord. When she returns, she needs to respect the scheduled hour and is submitted to breathalyzer. When the loser and insecure Clément, who has a crush on Mona, finds her job, he disturbs her, and she asks him to go away. Clément calls his best friend, the womanizer Abel, to help him to be with Mona, and they abduct her from the train. Without money to take a taxi to the prison, Mona stays with them along the night where the friendship of Clément and Abel is tested.
