Brotherly love is the focus of this film that explores how the relationship between big brother Mathieu (Vincent Perez) and kid sib Paul (Jérémie Renier) changes when the younger one becomes so enthralled by historical battle reenactments that he begins to lose his grip on reality. With his mother begging him to intervene, Mathieu -- a pianist -- attempts to steer his battle-obsessed brother in other directions. Denis Dercourt wrote and directed.
