A young woman, who is the daughter of a sea captain, falls in love with a man from a rich family who does not approve of her.

A child who wanders away from her parents is reared on board a ship by a kind old sea captain. She falls in love with a wealthy young man, but his parents scorn her as a "wharf rat" and forbid the marriage. After she is revealed as the long-lost daughter of their wealthy friends, however, the young man's parents willingly accept her into the family.—Pamela Short
