By Hook or Crook (1918)

Pampered Frederic "Freddy" Pritchard, warned by his father that he must work or be disinherited, learns how to crack safes to help his girlfriend Gloria Nevins, whose villainous uncle holds security for the family jewels, as well as the right to vote on the disposition of the Nevins Motor Works. After Freddy steals the papers with the aid of his valet Smithson, Gloria's uncle locks him in a warehouse to prevent him from attending a crucial stockholders' meeting. Freddy escapes and saves the factory for Mrs. Nevins, who gives him power of proxy. Pritchard, Sr., pleased with his son, consents to Freddy's marriage to Gloria.
