Armored Car Robbery (1950)

While executing an armored car heist in Los Angeles, icy crook Dave Purvis (William Talman) shoots policeman Lt. Phillips (James Flavin) before he and his cronies make off with the loot. Thinking he got away scot-free, Purvis collects his money-crazy mistress, Yvonne (Adele Jergens), then disposes of his partners and heads out of town. What Purvis doesn't know is that Phillips' partner, tough-as-nails Lt. Cordell (Charles McGraw), is wise to the criminal's plans and is closing in on his prey.
