The son and daughter of a well-to-do farmer, wearying of loneliness, aspire to locate in a big city. Frank, the son, receives an offer of a position in the city, and his sister, after much persuasion, is allowed to go also, to study art. They settle down in a boarding house and Frank soon becomes infatuated with a resident chorus girl, Nan Mosby, and consequently does not pay much attention to his sister, Edna. She, in turn, meets a wealthy artist, Herbert Knox, and he, impressed by her beauty, requests her to pose for him as a model. She consents, and gradually begins to fall under his influence. Her brother, Frank, is so much engrossed with his own affairs that he has no time to give to her, believing that her innocence and ignorance will be sufficient safeguards. One morning he tucks a note under her door, stating that he will not be home to dinner. A few moments later he receives a letter from his father asking him to return home at once, expressing anxiety over Edna. That evening the artist invites Edna to dine with him. She consents and they go to a café where Knox has arranged a private dining-room. In the adjoining room, Frank and Nan Mosby, are also dining. Knox orders wine, and Edna, ignorant of his intentions, drinks it. He soon becomes very familiar. He persists and she screams out her fears. Frank hears the cry and recognizes his sister’s voice. He breaks into the room, and hits Knox between the eyes. The latter staggers to his feet and demands to know by what right Frank interferes with him, and is met by the retort, “She is my sister.” The sinister artist looking at Nan, responds, “How about yourself? This girl may be somebody’s sister.” Frank then realizes the dangerous direction that he and Nan have been drifting. He takes his sister and Nan from the café, and leaves Nan at the stage door, shaking hands silently. The brother and sister then wire home. An hour later as the father and mother are preparing to retire, their phone rings and they receive the following message, “We are coming home for good.” The anxious parents bow their heads in prayer as the picture dims.
