In Vietnam, thirty years after the war, the ghosts of the past have not finished haunting the living: hundreds of thousands of soldiers have died without burial, reduced to the sad fate of wandering souls. Armed with their unit records, Tho and Doan, two former Viet Cong fighters, set out in search of the graves of their comrades, in the hope of bringing their bodies back to their families. From forgotten battlefields to cemeteries of "unknown soldiers", their quest takes them back to the places that marked their youth and forged their destiny.
