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.
Following a somewhat successful mission, Murn recruits Vigilante. Meanwhile, after learning that the team helped land his father in prison, Peacemaker confronts his complicated past.
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.
Harcourt, Murn, and Adebayo find themselves surrounded by an alien force, while Peacemaker squares off against his father with help from Vigilante and Economos.
