A welcome guest of the French aristocracy, Monsieur Picard having been awarded the Croix De Guerre, is also a master thief who baffles the Parisian police. One night, while Picard watches an Apache dance, he learns that one of his three adopted children is seriously ill. When his car breaks down, Picard politely forces Helen Deprenay to loan him her auto, and leaves his cross as security. The next day, the police pursue Picard to the Deprenay home where the prefect warns Helen about Picard. Helen writes to the entreating Picard, and refuses to see him until he proves himself of worth to society. Disguised as Scotland Yard agent Armand DuBois, Picard is present at the Deprenay home when a necklace is stolen. After Helen covers for him, Picard catches the thief in an attempt to swindle the entire community in a stock market scheme. He informs the police that Picard no longer exists, and escapes with Helen to a new life.

Slaving to perfect an invention, Noah Vale tries to keep two orphans--Rip and Patch--and himself by peddling books and is helped by Scallops, a girl who occasionally brings them food. He appeals to Fay, a wealthy relative, for help in marketing his invention and arouses the interest of Fay's pretty daughter. Sterrett, Fay's partner, steals the model but returns it when he discovers it to be worthless. Johnny Smith, Fay's secretary, is fired when he proposes to the boss's daughter; and visiting Vale's attic, he is comforted by his epigrams. Johnny takes them to a newspaper editor, and they are so successful that both Smith and Vale are hired. Vale decides to give up inventing for writing, and Johnny marries Miss Fay despite her father's opposition.
