On a dark night, the Japanese police is raided by a spy. Different countries' intelligence agencies—such as England's MI6, Germany's BND, and America's CIA—as well as the FBI's secret files are going to be taken, but public safety officers lead by Tooru Amuro arrive just in time. The spy steals a car and escapes. The spy and Amuro are then locked in a dead heat on the highway, and just as it is about to cause an accident with multiple cars, the spy's car is hit by FBI agent Shuichi Akai's rifle bullet and falls of the roadway. The next day, Conan and his friends go to a newly-remodeled aquarium in Tokyo. Under the main attraction, a Ferris wheel, Conan finds an attractive woman alone and injured. Her left and right eyes are different colors. But the woman is in a state of amnesia where she doesn't even remember her own name, and the cellphone she's carrying is broken. Conan and his friends promise to help her regain her memory, so they stay with her. Throughout all this, Vermouth is watching behind the scenes. Afterwards, she pulls out a silencer and speaks into an attached intercom, It's as planned, Gin.

Kaitou Kid dares to challenge the police once more, setting his sights on the Russian Imperial Easter Egg. With the date, time, and place, the Osaka police force scrambles to stop him. But this time, Kid may have bitten off more than he can chew—Conan Edogawa, Heiji Hattori, and numerous others are also trying to get their hands on the jeweled egg. As the race for possession of the egg escalates, a string of murders threatens those after it, and at the same time the tragic truth behind the Romanov Dynasty is finally revealed. At the center of these developments, it is up to Conan to solve the gruesome murders and catch Kid, all while protecting those close to him and concealing his identity.

The world's greatest blue sapphire, the blue lapis fist, said to have sunk in a pirate ship in the late 19th century, on the coasts of Singapore. A local millionaire plots to retrieve it, and when it's exhibited in an exhibition at the Singaporean Marina Sands hotel, a murder takes place. A bloody Kaitou Kid announcement card is found in the crime scene. In the meantime, Ran and Sonoko have come to Singapore to see a karate tournament held there. Conan, who doesn't have a passport and can't travel overseas, was supposed to stay at home. But Kid, who wants to make use of him, uses a magical trick to forcibly drag him to Singapore. Conan must obey Kid if he wants to get back to Japan, gets his glasses, wristwatch and clothes, amongst others, all stolen from him and he has to disguise himself. Ran, who doesn't realize who he is, asks him his name and he improvises the name Arthur Hirai. Kid eventually gets a hold of information about the fist being stored in a manor's underground vault. Just when he was thinking that he'd made it inside very easily, he finds a dangerous trap awaiting him. Facing him is the strongest karateka with 400 consecutive victories: Makoto Kyogoku.
