After his mother's death, John Gregory becomes the "Eagle," a thief determined to get even with the mining company that stole his family's fortune. No one suspects that he is a bandit, not even Lucy, the girl he loves, and her brother Bob. John finally breaks into the mining company's main office, but discovers that another robber has preceded him and killed the night guard. The robber is Bob, and when the boy is arrested, John interrupts the trial and takes the blame himself for Lucy's sake. Bob commits suicide, and Lucy, who discovers his written confession just before John is to be hanged, rides wildly to the jail and saves John's life.—AFI
