After having met and married after working together in HELL DRIVERS where they were basically glorified cameos, three years later David McCallum and Jill Ireland - as an aimless still at home loser hanging around a strip joint to catch that joint's top stripper -- actually starred in another B&W British flick that's far superior: a heist thriller that takes an entire film to reach that heist with creative twisty avenues, and our two stars aren't alone...
The third lead in the triangle is freshly-sprung convict Kenneth Cope, a handsome and experienced lad with a romantic background with Ireland (one scene as he charmingly converses with McCallum's kitchen sink mother is a standout); he also wants payback from former partner McCallum, who didn't get caught from what landed him in prison...
Meanwhile, Ireland's Sue is the obsessed apple of McCallum's wormy eye, and he has such comfortable means around the place -- constantly fixing the car of the club's pushy and obese owner, also smitten with the otherwise old fashion/idealistic Ireland -- and it's through McCallum's primary perspective the audience experiences this seedy locale, from the theater stage to random dressing rooms and offices, like really being there...

Enter Brian Weske's Joe Lucas as smarmy yet likeable hypochondriac Joe Lucas, also the most crookedly professional, having figured out who did the initial killing that everyone, including him, is being questioned for...
So as he darts in and out from random scene to scene, there's a palpable sense of Noirish criminal ambiguity that fits both the location and multilayered plotline -- one that needs more than one viewing to catch and thoroughly appreciate everything.
