In a trash-filled apartment, 24-year-old Akira Tendo watches a zombie movie with lifeless, envious eyes. After spending three hard years at one of Japan's "black corporations," his spirit is broken. He can't even muster the courage to confess his feelings to his beautiful co-worker Ohtori. Then one morning, he stumbles upon his landlord eating lunch-which happens to be another tenant! The whole city's swarming with zombies, and even though he's running for his life, Akira's never felt more free!
