Henry Allen (Lionel Barrymore) swears revenge when attorney Cortland Wainwright (Ralph Kellard) sends his innocent brother to the electric chair. After becoming an underworld bigwig, Allen discovers that Wainwright worships a girl he met only briefly, Maggie Flint (Gypsy O'Brien). The girl has a prison record, so he sends her abroad to be educated, then brings her back into Wainwright's life. After they marry and Wainwright is running for governor, Allen reveals Maggie's background, which, if exposed, will force Wainwright to give up his candidacy. But Maggie appeals to his better nature and Allen realizes that revenge isn't all it's cracked up to be. He backs off and leaves the couple alone.
