"The story of Robert Jordan (Cooper), an American demolition expert who lends his abilities to the anti-fascist freedom fighters of Spain. Assisting him is a band of warriors that includes the strong-willed Pilar (Katina Paxinou), the dangerously undependable Pablo (Akim Tamiroff), and the lovely, innocent Maria (Bergman). As danger mounts, Robert and Maria develop a closeness that blossoms into one of the screen's greatest love stories."--Container.
