The Amazing Woman (1920)

While vacationing at a hunting lodge, Ralph Strong, a recent medical school graduate, meets Anitra Frane. Their courtship is interrupted when the United States enters World War I and Ralph offers his medical assistance. Anitra, who has not been able to develop her beautiful singing voice in the country, goes with Ralph's father John to the city as his mistress so that she can pursue a singing career. After John refuses to marry her and sends her a check, Anitra becomes known as the seductress "The Flame," and decides to build a free clinic for children with money she gets from ultra-rich men. When Ralph's dissolute friend, Gaston Duval, kills himself because Anitra will not marry him, Ralph vengefully vows to find "The Flame." After Anitra convinces him instead to enter politics to cleanse the city of sin, Ralph is elected mayor. When he introduces his father to Anitra, she faints. After John has a heart attack and dies, Anitra confesses that she is "The Flame." Ralph says that he loves her and that they should strive together for a better future.
