King Solomon (Gino Cervi) sends his son, Prince Rehoboam (Gino Leurini) on a spy mission to Sheba where he falls in love with the beautiful Queen (Leonora Ruffo). He tries to prevent a war between their two countries, but after the Queen finds out that her lover is a spy, she leads her army in an assault against Jerusalem. The siege is a failure and ends with the Queen and Prince reuniting with the blessing of both King Solomon and Sheba's advisors.
