Jean-Pierre is a hit man in Paris. He wants to stop; an incentive is reconnecting to Michelle, a childhood friend. He's ready to commit himself to her, but she has her own secrets: she sells bomb components to thugs. He hears rumors of a missing briefcase, which he finds in Michelle's flat. He asks no questions, and soon both of them are in trouble with Jean-Pierre's ex-employer and with her bomb buyers. Two other characters complicate the maneuvering: Jean-Pierre's best friend, who's always losing money on the ponies, and the ex-employer's new contract killer, a seemingly fragile woman. Is there any way that Jean-Pierre can protect Michelle and escape with his life?
