Arriving in Baghdad, the crew, plus Fujiko, make it to the excavation site run by Marciano, and using their information, Lupin sneaks his way into the ruins overnight. After passing the boobytraps, he comes across a visage of a young Rosetta, claiming that she was sent to Earth by her “God” that appears every 76 years, which Lupin deduces is Hailey's Comet. He discovers what appears to be the ancient treasure of Babylon, a golden griffin, and manages to escape the crumbling ruins with it. Marciano and the hitmen attempt to claim the treasure for themselves, but Lupin flies away and escapes, only to be shot down by Fujiko who, accompanied by Rosetta, takes the griffin for herself. Lupin, Jigen, and Goemon continue their escape from the hitmen, as well as the ICPO girls, who had commandeered tanks from the local army, but they manage to escape on the ocean. Lupin then reveals that the griffin isn't the real treasure of Babylon, and it's really back in New York. At this time, Marciano reclaims the griffin and kidnaps Fujiko. Back in New York, Marciano's second-in-command, Kowalski, kills one of the hitmen for their failure. Lupin, Jigen, and Goemon dig up gold bars buried underneath Madison Square, the true source of the gold of Babylon. Lupin reveals 2500 years ago, the Tower of Babel had been somehow transported from Babylon to New York, which he theorizes is the work of either aliens or a "God". After excavating several of the bars, the gang are once again attacked by the hitmen, while another reappearance by Rosetta reveals Fujiko's kidnapping. Lupin breaks into Marciano's building to rescue her, when Kowalski suddenly betrays Marciano, killing him, planning to take over control of the mob before tossing Lupin and Fujiko down the tower. As they attempt to stop their descent, Lupin reveals to Fujiko the secret behind the treasure of Babylon, that "God" had collected all the gold he could and planned to take it back with him, but dropped it, with it landing somewhere in New York. They escape, while Kowalski is killed by a bomb in Lupin's packet of cigars, which he believed was a feint by Lupin from earlier. The following night, Rosetta uses her candelabra to send a signal to Hailey's Comet from atop Madison Square, as a UFO emerges from it, and the giant golden Tower of Babel is unearthed
