In military terminology, inner lines are escape routes which are located near opposing lines. They provide a way of passing undetected and fleeing. Around Mount Ararat, in Turkey and Armenia, messengers and their carrier pigeons travel along these parallel paths to meet up with communities in the grip of war. During their wanderings, they encounter Yezidis who have fled from the atrocities committed by Daesh and found refuge in transit camps in Turkey. They stand beside the last living survivors of the Armenian genocide. They travel around war-torn Nagorno-Karabakh, to accompany and support the bereaved families there. Throughout the story, men and women bear witness to what they have endured, to their shattered lives, to life, fighting off death. Above all, their words tell a tale of violence inflicted by men on other men, a violence that seems everlasting and obstinate.

Those who suffer from the melancholy of eternity are called eternals. Convinced that death cannot take their lives, they believe they are condemned to wander around waiting for the day when they will be released from their existence. This film is a tale of wanderings and escapes, on the borders of Nagorno-Karabakh, an Armenian enclave in Azerbaijan. Inhabited by the ghosts of the genocide and by the war that has been raging there for more than twenty years, the characters who traverse this film carry within them the melancholy of the eternal.
