Treasure of Monte Cristo (1949)

This modern tale borrows from an old story in establishing Langan, who works on a ship that docks in San Francisco, as a descendant of the Count of Monte Cristo. Crooked Lawyer Brodie sets up a scheme to get at the treasure of Langan's famed ancestor, and using the beautiful blonde Jergens, tries to lure Langan into a trap. Langan proves worthy of his heritage, using a gun instead of a sword, and wins legitimately both his forturne and Jergens.
