Chihuahua, Mexico, 1872. Blueberry seeks General Vigo, who can clear his name of stealing the Confederate gold. Blueberry, Red, and Jimmy are arrested because Vigo is now Governor. They'll be shot, until, with President Juarez dead, Vigo is to be shot. Blueberry enlists El Tigre's gang to help Vigo escape over the wall and jump into a hayrick. They ride to a waterfall and cave behind, having left the doublecrossing El Tigre in the lurch. Blueberry uncovers Vigo's stash and a receipt for the Confederate gold signed by Juarez himself!; Blueberry needs to clear his name and expose the conspirators out to assassinate President Grant. He gives General Dodge the receipt. In Alabama, he lures out Warden Kelly and learns of Delta Ranch in the Rockies. At the ranch, he's captured by the hideously scarred Angel Face. Red and Jimmy break him free, and they rush. The conspirators plan to blow up the tunnel as Grant's train passes. Blueberry bursts in and Grant is convinced when the tunnel blows. The conspirators are exposed and Mike Blueberry exonerated and rich. Next up - he's going to marry Chihuahua Pearl!
