To teach his fickle daughter, Jacqueline, the dangers of faithlessness, novelist Léon de Séverac reads her his latest story: In maneuvering for the favors of Zareda, a captivating Parisian adventuress, Baron de Maupin sends his son, Ivan, to war and takes the poison he intended for the Marquis Ferroni. Zareda marries the marquis, but she causes him to duel with Ivan, her true love, when Ivan returns. Ferroni is vanquished but lives long enough to imprison Zareda and kill Ivan.
