6 Angels

In the deserts of the southwestern United States stands "Neo Purgatory," a former nuclear waste disposal site repurposed as a high-security prison. When the inmates turn the radioactive waste into weapons and stage a violent uprising, the facility becomes a global catastrophe. The "Guard of Rose," an all-female special police unit, consists of Maki Aoba, Doris Nicholas, Marilyn Moreau, and Naomi Jones. While investigating rumors of an "angel" near Neo Purgatory, their helicopter is shot down, stranding them alongside stowaway Katherine Hook and the versatile robot Link. As the prison spirals into chaos, the Guard of Rose may be the last hope to prevent the prisoners from triggering a nuclear apocalypse.
