Violetta Duclos is a poor Parisian girl. After being struck by an automobile, she falls deeply in love with a young playwright, Alfred Germont. Called away by a family emergency, Alfred leaves Violetta, who, falling into more dire circumstances, is taken under the wing of the Graf (Count) von Geray. Von Geray promises her wealth and comfort. She initially rejects her rich suitor, but then, surprisingly, runs off with him. Alfred pursues her, only to learn that she has abandoned him not for lack of love, but due to serious illness.
