Old Captain Ward, who hates society, lives in the hulk of his ship with his granddaughter Sally, whom he prevents from meeting people. Because Sally's mother died in childbirth without revealing the name of Sally's father, the captain continually vows to avenge her death. When Sally finds Teddy, a lame dog, she smuggles it aboard, but it runs away, and she follows it to a beautiful house belonging to the famous Judge Gordon. Hugh Schuyler, the judge's young friend, and Sally fall in love. After the captain chases Hugh away, Sally attends the judge's party, dressed in fine clothes which the judge bought, but the captain finds her and takes her away. When the judge visits the captain and confirms his suspicion that Sally is his daughter, the captain attempts to kill him. Sally intercepts a blow, and awakens to find that the judge has proven that he secretly was married to her mother, but because of illness, had lost contact with her. Sally accepts Hugh's proposal, and they sail away with the judge, the captain, and Teddy and his family. -AFI
