From science fiction, historical fiction, to contemporary drama, Under the Air includes a variety of tales that depict the duality of man-good and evil; loving and violent. An injured white-supremacist struggles with the fact that he was brought back to life by a black organ donor; a young man in the wild west seeks revenge for his father's murder; an escaped convict holds a family hostage in a cave that causes hallucinations; the only two survivors of a nuclear apocalypse dare to explore the outside world-Tezuka's characters are put to the test when the delicate balance of their minds are disrupted, discovering something dark hidden deep within themselves.
