chunk: In late 1945, one-armed John J. Macreedy (Spencer Tracy) gets off a passenger train at the isolated desert hamlet of Black Rock. It is the first time in four years that the train has stopped there. Macreedy is looking for a man named Komoko, but the few residents are inexplicably hostile. The young hotel desk clerk, Pete Wirth (John Ericson), claims he has no vacant rooms. Macreedy is threatened by Hector David (Lee Marvin). Later, Reno Smith (Robert Ryan) informs Macreedy that Komoko, a Japanese-American, was interned during World War II.
