Stewart Granger

A 16th-century Spanish overlord hires Thomas Stanswood (Stuart Granger) to protect his, less than eager, fiancee (Sylva Koscina) from rebels. Thomas finds himself drawn to both the fiancee and the rebels side.

A kingdom's ascending heir, marked for assassination, switches identities with a lookalike, who takes his place at the coronation. When the real king is kidnapped, his followers try to find him, while the stand-in falls in love with the king's intended bride, the beautiful Princess Flavia.
