The Museum of Jewelry is holding a special exhibition of the diamond known as "Cleopatra's Tear." Lupin quickly makes a preliminary inspection, but with Zenigata showing up yet again, he has to run away. This was a planned appointment, so that he could hear from Zenigata the date and time of the diamond's delivery to the exhibition hall. Afterwards, Lupin and company conduct special blindfolded training in order to carry out their plan. The chance will only be for a few seconds, in pitch darkness. In that time, the four of them must successfully carry out a sequential, collaborative play, but will their labors bear fruit?
