Kiss of Death.

Jimmy Kilmartin's an ex-con who's trying to go straight. But he can't say no to a quick driving job because his so-called friend's life is threatened. The job is for Little Junior Brown, a violent and powerful villain. When things go wrong, Jimmy is left to do the time, and his whole life is turned upside-down, but if that wasn't enough, the cops won't leave Jimmy alone when he gets out... They want Little Junior Brown.
