Bad day at Black Rock

A one-armed stranger comes to a tiny town possessing a terrible past they want to keep secret, by violent means if necessary. -- IMDb

One-armed John J. Macreedy (Spencer Tracy) gets off a passenger train at the isolated desert hamlet of Black Rock in late 1945. He is looking for a man named Komoko, a Japanese-American, who was interned during World War II. Reno Smith (Reno Smith) is virulently anti-Japanese; he tried to enlist in the Marines the day after the attack on Pearl Harbor, but failed the physical exam. Smith and his henchmen are already there, as are Doc Velie and Sheriff Horn (Dean Jagger)
