In 1971, on the front lines of North Vietnam, American forces and South Vietnamese government forces were conducting Viet Cong mopping-up operations every day. Following in the footsteps of his father, who was a cameraman, Sam came to the front lines of Vietnam as a battlefield photographer. Absurdity occurs one after another in front of him as he boldly proclaims the antithesis of false justice. However, he overcomes his anger and sadness and tries to convey to the world the reality of Vietnam, which is mired in a quagmire, through the lens of his camera.
