Terry Malloy (Marlon Brando) could have been a contender, but now toils for boss Johnny Friendly (Lee J. Cobb) on the gang-ridden waterfront. Terry is guilt-stricken, however, when he lures a rebellious worker to his death. But it takes the love of Edie Doyle (Eva Marie Saint), the dead man's sister, to show Terry how low he has fallen. When his crooked brother Charley the Gent (Rod Steiger) is brutally murdered for refusing to kill him, Terry battles to crush Friendly's underworld empire.
