It's a love story that is most banal between two beings, Halvard (Gad Elmaleh) and Pollux (Cécile de France). Halvard Sanz meets Pollux and already considers her the woman of his life. But this one goes suddenly, without leaving a trace. To find this young lady, Halvard clings to the great principle of existence according to which we always meet "important people" twice. Stubborn as a fly, he will rush headlong against the great pane of life.
