Fritz Lang was one of the great silent film directors (His talkies are great as well) and this is his best silent film. Agents target the mysterious Haghi (Rudolf Klien-Rogge), a master criminal out to topple the banks of the world. The pursuit includes a seductive young female spy driving a Japanese business man to hari-kiri, assassinations, a chase and a showdown on a train (that collides in one heck of a sequence.) The film concludes with Haghi trapped on a stage where he is dressed as a clown (Why a powerful bank president moonlights as a third rate clown has always puzzled me.) Alfred Hitchcock openly cites this brillaint film as an influence. Also, there is a priceless glimpse of 1920's Germany here- the decadence of Berlin, where apartment dwellers turn their tiny flats into bars for extra cash. Even when the film plays in its complete 3 hour form, it's an exciting time at the movies.
