You're trapped in a locked room with every detective who matters, and the clock is real. Conan has solved impossible cases before, but this one was built specifically to break him, and he knows it. The movie doesn't waste time on filler, it's pure pressure, pure logic, pure desperation in a theme park designed like a coffin.

A mysterious invitation brings Kogorou Mouri, his daughter Ran, Conan Edogawa and the Detective Boys to the Miracle Land theme park. There, a mysterious stranger hands Kogorou and Conan an unsolved case to close. The invitation turns out to be a trap: Ran and the Detective Boys become hostages with bombs attached, and the detectives have twelve hours to crack the case before they explode. Worse, their captor knows Conan is really Shinichi Kudo. Heiji Hattori, the high school detective of the West, joins the effort, along with Kaitou Kid and even Saguru Hakuba. Racing the clock, they must untangle the clues, find the culprit and uncover who the client really is.
