This excellent film details the adventure of a man's search for his wife's killer and to clear himself of her murder. Harrison Ford is the hero and wanted man and on the run to escape capture by a determined U.S. Marshal in one thrilling scene after another. A spectacular train wreck with a bus of prison-bound felons gets the action underway at which point Tommy Lee Jones enters the picture and takes over the film by sheer force of personality and doesn't let go. Harrison, a resourceful type, stays just ahead of Jones in this taut cat-and-mouse thriller and adroitly leaves just enough clues for the police as he closes in on the killer. Ford and Jones are well matched here in one of the best urban crime mysteries ever filmed. Cast and Chicago locations add realism to a great story.
