Bounty hunter Brisco is hired by the West's most powerful robber barons to bring down the John Bly gang.

Brisco follows a lead on Bly to the town of Poker Flats and finds Bly, the orb, and an old friend who once left him to die at the hands of the Swill brothers.

Brisco and Socrates head south of the border when the Westerfield Club orders them to recover some stolen guns.

A figure from the future warns Brisco that Bly is going to escape from his orb prison.
