A sergeant (Marvin) in the 1st Infantry Division ( aka,”the Big Red One”) leads a squad of men through the horrors of World War II, from North Africa, to Omaha Beach and straight on to the liberation of a Nazi death camp. Four men survive the odds with him, including Pvt. Zab (Carradine), a cigar-chomping, brash writer, and Pvt. Griff (Hamill), a peace-loving naif. In between episodes of intense fighting, the soldiers battle fatigue, tedium and fear.
