XIII and Jones are on the run. Hunted by local authorities, they're suspected of three murders, including that of The Mongoose's hired killer. The sheriff of Green Falls, henchman to the town's biggest landowner, is all too happy to accuse the fugitives: The two men don't want certain details from the past to surface. XIII is going to have to survive long enough to dig up the truth about what really happened on the night of August 3rd long ago.
