Lupin is "invited" by a psychotic millionaire named Zylberstein, one of his old acquaintances, to a solitary chess game for life and death. To increase the thrill, Zylberstein has hired an infamous female sniper named Mirage, a former partner of Jigen, to kill Lupin during the game. This results in a deadly hide-and-snipe match between Jigen and Mirage amidst a ruined mountain city, which ends when Jigen manages to critically damage Mirage's rifle just as she is taking aim at Lupin and the resulting ricochet hits Zylberstein instead...
