Gary Cooper, Helen Hayes and Adolphe Menjou star in this classic romantic drama based on Ernest Hemingway's novel and directed by Frank Borzage. Frederick Henry (Cooper) is an American serving as an ambulance driver in World War I. When his friend Captain Rinaldi (Menjou) introduces him to the beautiful English nurse Catherine Barkley (Hayes), Frederick immediately falls for her. The pair share a brief idyllic interlude together, but the jealous Rinaldi does his best to come between them...

Robert Jordon is an American demolition expert who lends his unique abilities to the anti-fascist freedom fighters of Spain. Assisting him is a band of warriors that includes the strong-willed Pilar, the dangerously undependable Pablo and the lovely, innocent Maria.

As danger mounts, Robert and Maria develop a closeness, an interdependence, that blossoms into one of the screen's greatest love stories.

Their passion grows as they approach the hour of judgment - a climactic confrontation neither may survive.
