This has got to be one of the best crime / thriller movies ever made. James Caan is a superb actor, who when given the right role is in a class of his own. This film is his finest hour and he delivers a moving performance as the main character. Caan plays Frank who is an expert safe cracker with dreams of retiring and starting a family with his lady played by Tuesday Weld. He foolishly agrees to work for the mob headed by evil Leo (Robert Prosky), safecracking to order in the belief that after 2 or 3 big scores he can leave with a nice nest egg with which to start his family. When Frank decides it's time to move on and leave his life of crime behind him he soon discovers that it's extremely difficult to walk away when the big time crooks don't want to see their meal ticket leave. This film slowly builds up to a final, bloody showdown with the tension almost becoming unbearable as Frank realises that he is going to have to take drastic action if he truly wants out of his shady profession. Superb.
