Tone, who lives with her uncle Albertus, is in love with the Tellef, a poor sailor. Albertus sends Tellef to sea to prevent the relationship from developing. Tone becomes upset and promises eternal faithfulness to Tellef, and she rejects every suitor that comes to her. Albertus sends a letter to Tellef, who is in Pensacola, Florida, and says that Tone is planning to marry the bailiff. Tellef leaves the ship he is working on and then the ship is wrecked, and so everyone assumes that he has died. Tone holds herself to her promise of fidelity and moves in with Tellef's mother. A few years later, Tellef meets a friend from home in Pensacola, and he tells Tellef that the ship sank, Tone is still unmarried, and Albertus lied to him. Tellef travels home immediately, arriving just in time to prevent a foreclosure on his mother's house, and he and Tone are reunited.
