Ed tells them that Tom is involved with the robberies, so Pat goes undercover as a cook for the Jackson's cafe, when he learns that Ed killed their father, who was once Ed's partner, and stole his estate. After overhearing a stage driver talking to Pat about a stage full of money, Tom decides to ride after it, but Gene catches him by surprise, only to find that the real outlaw is ""The Black Rider"", who escapes in the mixup. Gene suspects Ed, and he is taken in, and the Jacksons receive their stolen estate.
