Doc Ido, a doctor and mechanic who lives and works in the hellish, postapocalyptic "Scrapyard," finds the—miraculously preserved—remains of a female cyborg in a junk heap. After he revives and rebuilds her, the preternaturally strong, amnesiac "Gally" begins to forge a life for herself in a world where every day can bring a fight for life.

The 1993 Gunnm anime adapts the first two volumes of the Gunnm manga.
