The movie is set on a state-of-the art Aegis vessel with the full cooperation of Japan's real-life Ministry of Defense and Maritime Self-Defense Force.

The heroine Ran is put in jeopardy, and Conan is forced to stand up against the dangerous Spy "X."

15 years ago, Daiichi Yachiyo Maru, a cargo ship, was crashed into a large iceberg in northern the Pacific Ocean, and sank. The captain and a crew were died. Now, in Nishitama, a ship designer of Yatsushiro Shipbuilder, which belonged to Yatsushiro Financial Combine, was suffered from a sudden heart attack while he was driving, and died in a traffic accident. Six months has passed since then. Conan, Ran, and Kogoro are enjoying their trip in the Aphrodite. The Aphrodite is a luxury liner, and it is sailing for the Pacific Ocean as its maiden voyage. However, there is a suspicious person, and finally a murder occurs. It is the beginning of a horrible plot occurred in the ocean where there is no place to escape from.

There is a sudden explosion at Tokyo Summit's giant Edge of Ocean facility. The shadow of Touru Amuro, who works for the National Police Agency Security Bureau as Zero, appears at the site. In addition, the "triple-face" character known as Rei Furuya, a detective, and Kogorou Mouri's apprentice, is also known as Bourbon, a Black Organization member. Kogorou is arrested as a suspect in the case of the explosion. Conan conducts an investigation to prove Kogorou's innocence, but Amuro gets in his way.

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 off 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."
