Armored Car Robbery(1950)

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