Writer-director Samuel Fuller applies his kino-fist to this raw-boned war drama -- one of the first American films to deal with Vietnam. The film concerns the battle between the Vietnamese and the Chinese, through the efforts of a small band of soldiers to locate and destroy a hidden communist arms depot. Gene Barry stars as Sgt. Johnny Brock, the cynical leader of the patrol, who is an American Korean War veteran. Leading the expedition to find the munitions dump is the half-Asian Lucky Legs (Angie Dickinson), Brock's ex-wife. One of Brock's less-endearing qualities is his rabid racism -- he can't accept the fact that their five-year-old son is completely Oriental in appearance. The other members of the patrol are also haunted by past memories -- Goldie (Nat "King" Cole) is a veteran of Korea and World war II who hates war and wants to see peace at all costs; Corporal Pigalle (George Givot) is an ex-French gendarme who doesn't like taking orders; and Private Andreades (Gerald Milton), is a hard-nosed Greek expatriate. When the patrol arrives at the compound, they are greeted by Major Cham (Lee Van Cleef), the communist commander who immediately falls in love with Lucky Legs -- complicating the situation immensely.
