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 gets help from his father's ghost when he tries to rescue a robber baron's son kidnapped by John Bly.

Bounty hunter Crystal Hawks aims to bring in Brisco, who's wanted for a killing he didn't commit.

Responding to a note from Prof. Coles, Brisco and Bowler end up on a collision course with Bly in pursuit of the orb.

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