In mid-1960s, groups of American paratroopers arrive at a Hmong village near the Vietnam-Laos border. Among the troops are former villagers who collaborated with the French; having returned home , they seek to win over the village’s support.

The main character in the film is a real person in history - the hero of the Vietnamese people's army, Cu Chinh Lan, set in the middle of the resistance war against the French (circa 1951) on the battlefield in North Vietnam.
