Build a movie plot around this: What does Janeway reveal herself as? that she was one of Szell's couriers.
Thomas Levy (Dustin Hoffman), nicknamed "Babe" in the film, is a history Ph.D. candidate researching the same field as his father, who committed suicide after being investigated during the Joseph McCarthy era. Babe is also an avid runner, which lends the film its title. Babe's brother, Henry (Roy Scheider), better known as "Doc", poses as an oil company executive but in fact is a U.S. government agent working for a secret agency headed up by Director Peter Janeway (William Devane). Babe is not aware of his brother's true occupation.Doc is often supposedly out of the country on business for extended periods of time but comes to New York under the guise of a visit to Babe. The brother of a Nazi war criminal possesses a safety deposit box key, but is killed in a traffic accident (after a road rage altercation with a short tempered middle-aged Jewish American motorist). Doc suspects that the criminal, Dr. Christian Szell (Laurence Olivier) will be arriving to retrieve an extremely valuable diamond collection. Szell later sends a burly assassin named Chen (James Wing Woo) to kill Doc in his Paris hotel room, but Doc fights the hit man and breaks his back.Babe enters into a relationship with a young woman named Elsa Opel (Marthe Keller), who claims to be from Switzerland. One night while out on a date Elsa and Babe are mugged in a park by two men dressed in suits. Some time later, Doc takes the couple to lunch, where he tricks Elsa into revealing that she has been lying to Babe about her background. Though Doc suspects she may have some connection to Szell, he tells Babe only that she is seeking an American husband so that she can become a U.S. citizen.After Szell arrives in America, Doc meets him to tell the former Nazi he is not welcome in the country, and also to warn Szell to stay away from Babe. Szell casually accepts the pronouncement, but then swiftly knifes Doc, wounding him severely. Doc is able to make it back to his brother's apartment, but collapses and dies in Babe's arms without telling him anything....
