Hearts in Bondage (1936) is a Civil War-era drama that blends historical conflict with personal struggles of loyalty and love. The story follows two naval officers and close friends—one siding with the Union, the other with the Confederacy—who find their bond tested as the nation fractures. Against this backdrop, their romantic entanglements and family loyalties deepen the emotional stakes.

The film dramatizes the build-up to the legendary battle between the ironclads USS Monitor and CSS Virginia, showcasing early naval warfare in one of the first cinematic depictions of the famous sea clash. With its patriotic tone, historical attention, and emotional themes, the film was Republic Pictures' first major production. Although less well-known today, Hearts in Bondage has developed cult interest for its unique setting, period detail, and the fact that it marked the directorial debut of actor Lew Ayres.
