On a dark night, the Japanese police is raided by a spy. Different countries' intelligence agencies - such as England's MI6, Germany's BDN, 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.
Unfortunately the movie Detective Conan: The Darkest Nightmare is not yet available on HBO Max.
