"The Stranger," a poor nameless scrub-man in a London pub, takes the blame for Larry Darrant's killing of Jim Walenn, an ex-convict who attacked Larry's fiancée, Peggy Bowlin, on the eve of their wedding. The Stranger, whom Peggy befriended, goes on trial, refuses to talk, and is sentenced to death by hanging. He has a heart attack on the scaffold and dies naturally just as Darrant is about to come forward to confess. Thus, Darrant's family name is saved from scandal, and the two lovers face a happy future.
