Canadian woodsman Jules Lamont leaves his wife, Zephne, after a misunderstanding and becomes infatuated with Joe Cateau's bride, a showgirl. Joe is killed when the two men fight, and Jules goes to prison, where he meets Pierre Lebec, an inmate who closely resembles Jules. When Jules learns that Pierre is about to be released, he persuades him to go to his own home and pose as Jules himself. Pierre does so and falls in love with Zephne, who believes him to be Jules. Pierre remains in disguise, "the man between," until the real Lamont returns and is killed. Then Zephne learns the truth about Pierre, and they marry.
