In a future where a massive catastrophe has devastated Earth, the majority of humanity has abandoned their physical bodies and relocated in digital form to DEVA, an advanced space station orbiting the ruined planet. Freed from the constraints of conventional existence, such as death and hunger, the residents of this virtual realm live in relative peace until Frontier Setter, a talented hacker, breaks into the system and distributes subversive messages among the population.
Deemed a security threat by the authorities, Frontier Setter is pursued by Angela Balzac, a dedicated member of DEVA's law enforcement. When the hacker’s signal is traced to Earth, Angela takes on a physical form, transferring her consciousness to a clone body and traveling to the world below to deal with the menace. On Earth, she is aided by Dingo, a charismatic agent, and during her quest to uncover the mystery behind Frontier Setter, she gradually reveals startling truths about the wasteland that some of humanity still calls home, as well as the paradise above.
