Quite a complex crime thriller directed by and starring Mark Stevens ("Charlie Norman"). The gist being that a gang steal $500k from a moving railway train. The insurance company put their ace investigator "Norman" onto the case with his old pal "Joe Armstrong" (King Calder). Soon it is quite clear that something is amiss and “Armstrong" becomes suspicious that his buddy might be more involved than he ought to be. The supporting cast benefit from a little more character depth than we might expect from this low budget affair and are superb in keeping it moving along sharpishly; there are plenty of crumbs for us to follow and the dialogue is quick and to the point.
