Redhead

A bus driver feels terrible because he let off an innocent woman at the wrong place and she got killed, so he uses his contacts to hunt down the killer.

Harry is a has-been prize fighter whose only major handicap is the color red. Like a raging bull, Harry goes crazy whenever this bright color shines his way, and he is driven to knock out his opponents, including innocent redheads he’s never met.

In order to assuage his guilt over the death of an innocent woman whom he dropped off at the wrong stop, a bus driver uses his connections to catch the murderer.
