Black Friday: In 1869, enemies of railroad magnate Richard Strong attempt to ruin him. Richard thwarts them, largely through the help of Charles Dalton, but then Charles tries to seduce Elinor, Richard's wife. Although she rebuffs Charles, Richard accuses her of infidelity, so Elinor leaves him and goes to Paris. Richard follows her, but, caught in the middle of the 1870 riots, he cannot get near her. Charles, also in Paris, finally convinces Richard that nothing had come of his interest in Elinor, but Richard now believes that Elinor no longer loves him.
