Trama

Carroll, cruising in his yacht, finds it necessary to put in at the shipyard of Fulton for some minor repairs and his little daughter, Miriam, meets the shipbuilder's boy, Frank. Childlike affection results and Carroll hurries Miriam away, explaining that she is a little lady and mustn't associate with shipbuilders' sons. Fifteen years later Frank is in technical college and Miriam in a fashionable university. Frank's chum, invited to the university, brings Frank, and Frank and Miriam meet, fall in love, and plan to marry, ignorant of the fact that they ever met in life before. Carroll consents on condition that they wait until Frank makes good in the world. Carroll and Miriam leave for another cruise. Fulton calls Frank home as Alexander, a rival, is taking away much of his business through crooked work. Carroll again puts in at this harbor for repairs and Alexander bribes the captain so that, when Carroll discovers that Miriam's lover is Fulton's son, he is led to promise Alexander the work. But the discovery of Alexander's bribe switches Carroll to Fulton again, when Fulton promises to keep Frank away during the yacht's stay. Frank's hobby is motor boats, and, suspecting further crooked work on the part of Alexander, He uses the boat on some detective work and finds that Alexander has become the victim of some revolutionary agents, who, to smuggle ammunition into their country, plan to steal Carroll's yacht. Carroll refuses to heed Frank's warning, but Miriam rushes down to the boat and is carried away when it is stolen. Frank pursues the conspirators in his motorboat, carrying Fulton and Carroll, and wins Carroll's approval of the match.—Moving Picture World synopsis
