In a stark portrait of rural Turkish life, "Aga" follows three brothers bound by their shared existence: Salim and Veysel, shepherds who toil in the village, and Şenol, forced into domestic duty after his educational ambitions are crushed. As the ties that hold them together begin to fray, a sense of desperation builds, culminating in a heart-wrenching confrontation that will alter the course of their lives forever.
