The Narrow Margin - A cop is assigned to protect a witness who is going to spill the beans on some very important dangerous people. They get onboard an L.A. bound train where's she's scheduled to testify. Unfortunately, some hired guns managed to follow them right onto the train and are trying to do anything to knock this woman off before they make it to L.A. However, they haven't been able to identify this witness, but they do know the cop who they now hope will lead them right to her. What follows is a suspenseful cat and mouse game as our cop hero tries to outsmart these killers onboard this rumbling locomotive and get this witness to court in one piece. I take a look at director Richard Fleischer's 1952 classic B-Movie film noir The Narrow Margin starring Charles McGraw and Marie Windsor and its 1990 remake Narrow Margin starring Gene Hackman and Anne Archer.
