Lupin III: Part 6

Synopsis

Lupin visits Mattea who is recovering at the hospital, although she is not surprised to learn his true identity. Fujiko arrives to reveal that the group of female thieves is called "Elvira" and their leader is Mercedes Camilo. She explains that their next target will be the Banco Alban Bank in Mexico within five days, but Lupin suspects he is the real objective. On the way, Lupin explains to Jigen and Goemon that Tomoe is not his biological mother, but a teacher assigned by his grandfather to see if he was worthy of the "Lupin" name. He considered her as a mother-figure, however she apparently stole his grandfather's treasure, but was caught and shot, falling to her death. On the day of the raid on Banco Alban, Elvira overwhelms Zenigata and the police force with tanks, successfully robbing the bank, but Jigen plants a tracker on them. Lupin and the gang break into Elvira's hideout, and after several attempts to outsmart each other, Lupin defeats Mercedes and reclaims his treasure. She claims that she was also trained by Tomoe, whom Lupin now suspects faked her own death. Zenigata arrests the Elvira gang, while Lupin allows Mercedes to live, however he vows to find out if Tomoe is alive and the truth about the night she apparently died.
