Gene Hackman and Anne Archer star in a good thriller that has tense moments and wonderful Canadian scenery. The story is of a frightened woman who sees a man killed and takes flight to avoid having to appear as a witness to a murder. Hackman is the resourceful district attorney who convinces Archer to return to Los Angeles and testify against the killers. The rest of the picture details a game of cat and mouse between Hackman, Archer and their pursuers who see Archer as a loose end and are determined to keep her from the courtroom. The scenes of pursuit atop the moving passenger train have been done in other films but is expertly done here without becoming a cliché. The picture does have its flaws but is a diverting film and any movie starring Hackman is certainly worth watching.
