After surviving being shot and then buried beneath a collapsing building, Peacemaker returns home only to realize that his freedom comes at a price. He is now part of Amanda Waller's new team fighting a mysterious new threat. Can he eliminate the threat without making things worse?

Following the exposure of Project Butterfly and the disbandment of Task Force X, the 11th Street Kids grapple with new identities, new friendships, and new rivalries. For Peacemaker, this means reconciling his past with his newfound sense of purpose — here and in an alternate dimension. Meanwhile, Rick Flag Sr. reappears as the director of A.R.G.U.S., focused on controlling metahumans and avenging the death of his son at the hands of Peacemaker.
