"Lupin III: Secret Files" is actually a compilation of two previously unreleased works and three film trailers. The first unreleased work is the original pilot film which was to be Lupin's anime premiere, but was replaced by the TV series. The second is a remake of the pilot which, for unknown reasons, also went unreleased. The trailers are for the first three Lupin films: "Lupin vs. the Clone", "Castle of Cagliostro", and "Legend of the Gold of Babylon".
