The mystery collapses halfway through, leaving only what this movie actually cares about: Conan and Kaito Kid circling each other across Singapore's skyline while everything explodes in precisely-drawn angles. Animation this sharp makes even a predictable heist sing. This is a franchise movie that knows exactly what it is, not a puzzle to solve, but a spectacle to watch unfold.
A legendary sapphire lost at sea for over a century surfaces in Singapore, and suddenly everyone wants it. When a wealthy collector displays the gem at Marina Bay Sands, someone dies, and a calling card written in blood points to one culprit: the phantom thief Kaitou Kid. Conan arrives expecting a straightforward heist, but the pieces don't fit. Kid claims he's not behind the murder, and he's usually honest about his crimes. Someone else is using the thief's signature to cover their tracks, and they're willing to kill to keep the sapphire's secrets buried. Conan teams up with an unlikely alliance of detectives, con artists, and thieves to unravel what really happened at the hotel. As they dig deeper into the sapphire's history, rival factions close in from all sides. Trust becomes currency nobody can afford, and the line between hunter and hunted blurs in Singapore's glittering underworld. The case demands more than deduction: it demands understanding why someone would kill for a stone, and what price that stone has already claimed.
