Lupin III

Within one of Lupin's back teeth, a piece of microfilm containing the location of the grave of Lupin I is concealed. Using a nude operation, Fujiko takes it, teams up with Holmes III, and together with three secret agents representing the U.S., Great Britain, and the U.S.S.R., they take to the sky in a gigantic hot-air balloon. Lupin, Jigen, and Goemon fight the secret weapons of the three agents, meant to eliminate interference, with the "Live Capture" technique(?!) taught to them the hard way by Zenigata. Where is the treasure? Who is the thief?
