Set in present-day Tokyo, this single-episode action OVA takes place aboard the Lightning L808, a new Japanese luxury airliner. On an apparently ordinary flight, Haruka Leina and her fellow passengers have no idea that a secret, dangerous cargo is on board. International terrorists want that cargo, and the flight turns into a hostage crisis. Special agent Laika Strange and the courageous Leina may be the only ones who can rescue the passengers and keep the cargo out of the wrong hands. The story is the fourth and last OVA in the Leina spin-off of Machine Robo: Revenge of Chronos, and it is set in a separate universe from the earlier Wolf Sword Legend storyline.
