Lupin goes from stealing to being stolen in the middle of an aerial robbery when he is dragged off and compelled to undertake a task for a mystery man identified only by the brand of cigarette he smokes. Lupin's mission: to take the notorious "Bull's Eye," a little green diamond so infamous that everyone who has ever stolen it has died. Along with escaping and following a teenage burglar with a competitive drive, Lupin and the gang must solve the riddle of the Bull's Eye before its curse - or their mysterious taskmaster - overpowers them.
