Assault Girls tells an action-packed post-apocalyptic story set on a desert battlefield, and featuring three hot chicks armed to the teeth - Gray, Lucifer and Colonel - as they fight giant monsters named "Suna Kujira" (sand whales). Mamoru Oshii previously wrote and directed a couple of "Assault Girls" short films, but this will be his first full-length live-action movie since 2001's Avalon.
