An impertinent son of a wealthy New Yorker, Roger Carr takes the blame for the murder of Norman Evans, whom Roger believes his sister Ethel shot when Evans assaulted her. Although Ethel, who was unconscious, confesses to protect Roger, whom she thinks is guilty, Roger is sent to prison, and Ethel goes to a California mission. Upon his release, Roger is disowned by his father. He goes to Arizona, and after buying a copper mine, becomes the leader of the independent owners opposing the trust. After Roger instigates reforms favoring the workers, the trust reveals Roger's past. Meanwhile, Jarvis, the Carr butler, who became a gardener at the mission, gives Ethel a confession of murdering Evans, before he dies from injuries suffered in a tornado. After Ethel clears Roger's name with the confession, Roger, with the help of his stenographer, Mary Tompkins, reveals a strike leader as a tool of the trust. Roger is elected to Congress and takes Mary as his wife.
