Although Esther Whitaker is in love with Caleb Tilden, her sea captain father demands that she marry his first mate. However, Esther's grandfather encourages her and Caleb to marry in secret. After Grandfather Whitaker's death, Esther discovers she is pregnant. The captain, believing that she has disgraced the family, beats Caleb to death (at least that's what he assumes) and drags his daughter along on the ship. Afraid of the consequences, the captain refuses to go home and eventually the crew mutinies.
