The warship Aegis Destroyer is conducting public exercises in Maizuru Bay where, coincidentally, a suspicious foreign ship was recently spotted. Conan Edogawa, Ran Mouri, Kogorou Mouri, Sonoko Suzuki, and the Detective Boys all receive a ticket to attend this event. However, while the ongoing military operations are underway, one of the crew members comes across a lieutenant's severed left arm. Conan later discovers that a foreign spy may have infiltrated the warship to obtain classified information by any means necessary. If the information were to leak, Japan's line of defense would be exposed, leaving the country unprotected from hostile attack.

With the help of the police at sea while other friends and allies investigate on the mainland, Conan must now prevent this national crisis and identify the spy for the sake of Japan.

One morning, at the observation deck of the Bell Tree Tower, a man is suddenly shot dead by an unknown sniper. Conan Edogawa, who happened to be visiting as the murder occurred, rushes to apprehend the sniper but fails to do so. He later learns that the suspect for the incident, Timothy Hunter, is a former member of the Navy Special Ops squad and was already being investigated for a previous murder case. The FBI believes that there are at least three people Timothy wants dead. However, after the deaths of two of them, Timothy himself is killed, throwing the investigation into disarray.

As they lose their only lead, news about the assassinations spreads across Tokyo, leaving the city in a state of panic. It is up to Conan to find and catch the culprit in the hope of putting an end to this sniping spree terror.

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."

Nobita has been having a weird dream about a boy named Roppel and his strange companion Chami traveling in space. By a twist of fate, he met them in person where it turns out that they are real and that they were being pursued in space, causing their space vehicle to malfunction, connecting the space vehicle itself with Nobita's room. They journeyed to Roppel's planet and amidst their enjoyment, Nobita and Doraemon pledged to help Roppel's planet free from their oppressors.
