In a France uneasy after the terrorist attacks at the Bataclan concert venue, many citizens gather one Saturday to make their voices heard. Among them are three teenagers who support the protest movements: Apolline, J.B., and Harley. Others have come to bear witness like Samia, a Youtuber come to film and interview demonstrators. Also present is Aurélien, a helpless victim caught up in the violence and chaos despite himself as the protest degenerates into pitched battle.
