One morning, a worn-out field cop, nicknamed Ping-Pong by everyone, burns his police ID and disappears. During one night and one day, his colleagues look for him, meet him and lose him in Toulouse and its suburbs. But every hour that passes brings Ping-Pong a little bit closer to his own destiny.
A simple and quiet young man, Ruben faces the ups and downs of his life. But now, in the family, the “lame duck” is his brother. He allowed himself to be drawn by a gang of thugs into a high-risk enterprise. After being badly beaten in a beating, he finds himself between life and death. Fatally invested with a brotherly duty, Ruben goes to find the thugs to try to remove them from his "brother" and put an end to this story. But what was supposed to be an end turns out to be a nightmarish departure.
