Lieutenant Colonel Lam is an American army officer given a top secret mission by the US military. The mission entails entering Vietnam to destroy an old American bunker filled with missiles before the Viet Cong can get to them. Due to the dangerous nature of the mission, a group of Chinese American soldier convicts are selected to accompany him, led by Tung Ming-sun. Survivors are promised a pardon, U.S. citizenship and $200,000each. After a brief training session they are dropped into Vietnam. During the jump, Lam learns too late that the mission has been aborted. Once in enemy territory, they are met by some Cambodian guerrillas led by Godenzi and take refuge in a small town. There they meet Weasel (aka Chieh Man-yeh), and his mentally ill "Uncle", Yeung. Later, the squad is captured and incarcerated in a POW camp, where the prisoners are forced to play Russian roulette in a similar manner to the film The Deer Hunter. After escaping, they discover that one of the Cambodian guerrillas is a traitor. With the Vietnamese military in pursuit, they are able to reach the bunker, where a final showdown with the (giggling) Vietnamese general occurs.
