After creating her army, which she calls Copperheads, she has her subordinates, Johnny Vermillion and Stamper, begin leading them to the town of Harper's Junction.

Daisy and Billy encounter Johnny and capture him but with the sheriff dead and the town overrun, they decide to take him with them as they head to Desert Springs.

He does, and they plan their escape, but before he leaves, Johnny pays a visit to Georgie, a young boy that Cooper is raising.

They arrive at the mines at the base of the mountain and Billy wants to go around them but Jack says they need to search the place as a friend had a stash of ammo hidden there.

Sirene leads them up the mountain and when they stop for the night, she tells them about where the Copperhead name came from, and how her grandmother taught her how to track and hunt.

Johnny tells Apocalypta that he has the heroes trapped and she unleashes her army to attack Desert Springs.

They manage to escape and trap the Copperheads in the mine and head back to try and save Desert Springs.

Jack manages to kill Apocalypta and as he watches the Copperheads feed on her body, he is bit by a small child.

With Apocalypta dead, humanity has a chance to come back from the apocalypse while Sirene is shown to have given Jack a sky burial so his spirit can be reborn.
