Saboteur is a 1942 American spy thriller film directed by Alfred Hitchcock with a screenplay written by Peter Viertel, Joan Harrison and Dorothy Parker. The film stars Robert Cummings, Priscilla Lane and Norman Lloyd. Plot Barry Kane is falsely accused of torching Stewart Aircraft Works in Glendale, California, an act of sabotage that incinerates one of his co-workers. Barry believes the real culprit is a man named Fry, but investigators find no such name on the employee list. Thus Barry becomes the target of a manhunt. While eluding capture, he remembers Fry's address from an envelope, so he thumbs a truck ride to a huge ranch in the High Desert. While there, he learns the whereabouts of Fry and that the ranch's owner, Charles Tobin, is collaborating with Fry and other saboteurs. Barry escapes the ranch, later taking refuge with a blind man whose niece, Patricia Martin, attempts to betray him to police. Barry insists he is innocent and kidnaps Patricia. This leads to a series of adventures that take the couple from one end of the country to the other. Barry and Patricia stow away on a circus caravan, whose members conceal the pair from authorities. Eventually the two reach Soda City, a desert ghost town, where they separate. After infiltrating Tobin's spy ring, Barry learns the saboteurs are preparing to disable a new battleship at the Brooklyn Navy Yard. Meanwhile, Patricia contacts the nearest sheriff, who she later discovers is on Tobin's payroll. Tobin and associates retrieve Patricia from the sheriff and take her to New York. At the same time, Barry and the saboteurs travel to New York and meet with Tobin and the captive Patricia at the posh home of a rich sympathizer, Mrs. Sutton. Later, Tobin's organization imprisons Patricia in an office high up Rockefeller Center, while Barry is locked in the Sutton basement. He escapes by triggering a fire alarm. At the same time, from the multi-storied office building, Patricia floats an SOS note out a window. It lands next to a group of cab drivers who read it and notify police. Barry rushes to the Navy Yard and locates Fry at the controls of a device designed to blow up the battleship. In the ensuing struggle, Fry successfully presses the button that sends the ship to the bottom of the harbor. Fry then escapes. After terrorizing a movie audience at Radio City Music
