Shakedown (1950)

Jack Early is a photographer who will stop at nothing to climb his way to the very top of the success ladder. On the strength of his sheer tenacity, he gets a job with a major newspaper, and it's not long before he's made a name for himself by charming a notorious crime boss, Nick Palmer, into allowing himself to be photographed. Palmer takes him under his wing, but Early decides to bite the hand that feeds him and sets Palmer and another crime boss, Colton, against one another.
