The Plunger (1920)

When "Take A Chance" Schuyler rises from a Wall Street office boy to a wealthy investment broker, he purchases fellow broker John Houghton's estate. Houghton's funds have been depleted from blackmail payments made to his former employee, Norman Yates, who, out of revenge for Houghton's refusal of his daughter Alice's hand in marriage, has convinced the broker that he has committed a murder. When Schuyler arrives to take possession of the estate, he is surprised to find it still occupied by the Houghtons. At first, Alice resents Schuyler as an interloper, but she begins to change her opinion when the young broker protects her from Yates's threats. Yates retaliates by attempting to ruin Schuyler who then forces the blackmailer to admit that he actually was the killer. Houghton is thus exonerated and Alice and Schuyler marry.
