Plot hole: The film takes place around 1980, i.e. when it was filmed. But Steve Railsback appears too young for the Vietnam veteran he is playing, and in any case he has meant to have come back from the war, immediately committed a crime, and been on the run since. This would only be possible if he had been on the run for a decade, with the police in hot pursuit for all this time: that is extremely unlikely. These inconsistencies are actually a reflection of the fact that the film was scripted a decade before it was shot.
