Thornhill sneaks onto the 20th Century Limited train. He meets Eve Kendall (Eva Marie Saint), who hides him from the police. Kendall and Thornhill begin to establish a relationship but Kendall, unbeknownst to Thornhill, is actually working with Vandamm and his thugs. In Chicago, Kendall tells Thornhill she has arranged a meeting with Kaplan at an isolated bus stop. Thornhill waits at the bus stop, but Kaplan never shows up. He is then attacked by a crop duster plane.
