Riff-Raff is a 1947 black-and-white film starring Pat O'Brien, Anne Jeffreys and Walter Slezak. Considered a minor film noir entry more in the adventure genre, it was directed by Ted Tetzlaff, who later directed The Window (1949) and worked as a cinematographer for over 100 films, including another successful suspense film, Alfred Hitchcock's Notorious (1946). The music was composed by Roy Webb and Joan Whitney.


A cargo plane leaves Peru, bound for Panama with two passengers during a storm. When one of the two pilots goes to check on an opened door, Charles Hasso (Marc Krah) claims he tried but failed to prevent the other passenger from jumping to his death. Upon landing, Hasso is questioned by Major Rues (George Givot) of the Panamanian secret police, but is released as there were no witnesses. Hasso takes with him the deceased's briefcase, in which he finds a map.
