Tom Adams gives a masterful performance as a ruthless, cold-blooded and thoroughly brutal criminal mastermind in this vastly underrated crime study. We see him conceive of the plan of a seemingly impossible bank heist, meticulously plan every necessary move to the last fraction of a second, and set about assembling the most expert and competent criminal personnel to pull it off successfully...a race car driver, explosives expert, killer marksman, etc. After perfecting their parts through precision timed rehearsals, they successfully execute the robbery which will make them each rich....and then the betrayal begins. This is a film with a cold, dispassionate core. Michael Culver, in a supporting role as one of the participants who genuinely loves Adams' two-timing abused mistress, is the only one with any redeeming human qualities. Nevertheless, enough interest has been generated for the viewer to be surprised at the abrupt and unexpected conclusion.
