After receiving $50 for performing a dangerous dive at a swimming fete, Mira Sacky, the daughter of a music master whose legacy to her was the potential to be a great singer, decides to pursue others ways of getting money. When she rescues a boy from drowning, wealthy Michael Ordsway, a friend of the boy's mother, tells Mira to name her reward. Remembering her father's advice not to accept money from any man to whom she does not have a just claim, Mira requests, to Michael's discomfort, that he marry her. He gives in when she calls him a welcher, and she offers to leave if he will give her $10,000. He refuses and after a misunderstanding, they separate. Michael's father, encouraging her to seek voice training, gives her the money. Three years later, Michael, searching in vain, visits his sister in Rome and discovers that Mira has become a famous singer. They confess their love and resume their marriage.
