Detective Conan: Strategy Above the Depths

Fifteen years prior, a cruise ship vanished after hitting an iceberg in a remote part of the Pacific Ocean. Years later, Hideto Yashiro, a ship engineer connected to that incident, died in a car accident. This connection remains unknown until the luxury cruise ship St. Aphrodite embarks on its first voyage. Onboard for a vacation arranged by Sonoko Suzuki's family are detective Kogorou Mouri, his daughter Ran, Conan Edogawa, and the Detective Boys. Their trip takes a serious turn when, during a game of hide-and-seek, Sonoko suddenly disappears, prompting an investigation into the mystery tied to the ship's past.
