Three kolbars—cross-border porters who smuggle goods along the treacherous mountain frontier between Iran and Iraq—carry immense loads across paths so steep that even mules cannot pass. Here, only human shoulders remain, enduring a grueling journey that unfolds on the threshold between life and death. The film follows three men. Eyyup once played a smuggler in a film years ago; today, he has become one. Ata dreams of painting and art. Ako is a kung fu athlete who uses the money he earns from this illegal work to pursue his passion after nightfall. Hauling fuel, fabrics, and cigarettes across the mountains, they embody a quiet resilience and an unwavering determination to build a better future for themselves and their families. Through immersive images that capture the exhausting rhythm of the ascent and descent, and the endless caravans of porters moving beneath majestic yet unforgiving snow-capped peaks, the film becomes a powerful meditation on dignity, endurance, and the ways personal passions can sustain the human spirit under the harshest conditions.
