After making a miraculous recovery, Peacemaker returns home only to discover that his freedom comes at a price.

After Peacemaker's hazardous escape, tension and mistrust build within the team. Later, as Peacemaker grapples with his new assignment, he receives a surprise visitor.

On their first official mission to assassinate suspected "butterflies," Economos and Murn bond, and Peacemaker and Harcourt reach an understanding. But the whole job goes sideways with the arrival of Judomaster.

The team scouts the apparent hub for the aliens' food supply, only to come face-to-face with a full-fledged invasion. Meanwhile, Auggie's attempt to sell out his son to the police is complicated by Murn's mysterious contact.

Murn reveals his deepest secret; Auggie is set free; the botched arrest of Peacemaker sends alien Goff into an unexpected new host.

Harcourt, Murn, and Adebayo find themselves surrounded by an alien force, while Peacemaker squares off against his father with help from Vigilante and Economos.

Although Peacemaker and Adebayo are at odds, the team must kill the cow before the aliens can finish its teleportation.
