In a country recovering from a brutal and divisive civil war, a young boy, Jamie, is knocked off his bike and dies in a city street. His father agrees to allow one of Jamie's lungs to be removed and flown over the border for a transplant. As the night unfolds and the plane travels across the war-ravaged country, we see the drama from three different perspectives: the father, grieving for the son he perhaps never knew well enough; the lung's recipient, an old man fighting for breath; and in the turbulent sky between them, the young pilot who is closest to Jamie - or at least to his breath, his spirit, his voice.
