After a zombie epidemic, life on earth develops inside fortress cities that none are permitted to leave. Repression becomes routine, unchallenged by a frightful society. A small group of punks dares to defy the city's authority, determined to prove that the state exploits the fear of the people.

A mob denounces Demian as a terrorist because of his hairstyle. He manages to escape with the help of the so-called terrorists—and a little teargas. The group concludes that only Demian can help them escape a certain fate, but he's hesitant to help.

Demian's exoneration could lead to certain death for the alleged terrorists he'd been trying to help. The group finds itself driven underground after a nasty battle with governmental robots.
