The episode starts when Shinichi, Ran, and Kogoro wake up trapped in a white cubical cell with no recollection of how they arrived there. A letter in the room reveals that an admirer of Shinichi's detective work placed him there to test his deduction abilities. Soon, a panel in the room turns on, revealing with the date June 24, 2010 and a password to key in. Shinichi recalls an investigation that occurred on that day, when a famous photographer murders his lover. The case starts where the famous photographer, Tsubochi Yuhei and Kishi Kousuke was hit by an unknown robber after murdering a model, Aida Momoko who turns out to be Tsubochi's lover. However, Shinichi uncovers the truth that Tsubochi staged a robbery scene to hid the fact that he murdered his own beloved because he assumes she cheated on him with another man. Shinichi also reveals that he killed her due to a misunderstanding as the pictures in Aida's camera reveal a hidden message saying that she still loves him. Back in the white room, Shinichi keys in the word "I love you" and the door opens. However, it leads to another room with the same panel only with the date September 2, 2010 and a levitating spoon in the center of the room.
