Signor N. Salerno

A corrupt art patron finds himself in love with the same girl as his stepson.

Singer Rosa Roma signs a contract with backer Ogden Ward, forbidding love, public appearances, and using her real name. She breaks the contract by falling for composer Griffith Ames, starring in his opera, leading to conflict, a stolen ruby necklace, false accusations against Ames, and ultimately, their reunion after the real thief confesses.
