Ghost of Zorro (1949)

It is 1865 and the telegraph is heading west. George Crane, wanting to keep law and order out of his territory, is out to stop the construction. The engineer on the job is Ken Mason and he is the grandson of Don Diego Vega (also known as Zorro). As Crane sends his men or Native Americans to stop the work, Mason repeatedly puts on the Zorro costume and rides to the rescue in this twelve-chapter serial.
