Detective Conan: The Latest Theatrical Version 17

Title: 'Detective in the Absolute Sea'

Synopsis:
On the sea surface illuminated by the morning glow, a mysterious ship loaded with bombs floats. This ship is the beginning of everything...

In the waters of Maizuru Port, Kyoto, the Japan Maritime Self-Defense Force held an event where ordinary citizens could board Aegis destroyers to experience sailing activities. Conan, Ran, Kogoro Mouri, and the Detective Boys also participated in the event, joining children gathered from all over the country, and were shocked by the immense power brought by the high-tech battleship equipped with electronic weaponry.

Suddenly, a massive explosion rang out, and a tense, uneasy atmosphere spread across the vessel. Had the Aegis destroyer actually fired live ammunition during the demonstration?! Soon after, a body missing its left arm was found floating on the sea... and it turned out to be a Self-Defense Force member! Moreover, there were some suspicious traces left at the scene...

Stepping forward to investigate, Conan learned that a spy from a certain country, 'X', had already infiltrated the ship. Who exactly is this spy 'X'? What is their connection to the suspicious ship? The spy's presence has already lurked close to Conan and his friends... Someone is reaching out to Ran with malicious intent! Conan faces an extremely dangerous emergency mission!

Even more shocking, the spy's target is actually the entire country of Japan! The huge conspiracy hidden in this voyage far exceeds imagination and will shake the whole of Japan!

Clever detective vs. cunning spy – who will prevail?!
