The Big Steal (1949)

Army officer Duke Halliday (Robert Mitchum) is headed to Mexico to track down a con artist named Jim Fiske (Patric Knowles). Along the way, he meets the beautiful Joan Graham (Jane Greer), who, like Halliday, was double-crossed by the shifty Fiske for a large sum of money. Complicating their search is Vincent Blake (William Bendix), a military man out to get Halliday, and Ortega (Ramon Novarro), a police inspector who is patiently waiting to see how the various conflicts play out.
