Onda and Suemura were murdered by Yonekura over the robbery the four of them committed 10 years ago. Onda was blackmailing Yonekura, who then plotted to murder all of his former associates. Later, it becomes clear that there was a fifth robber. Conan and Heiji are certain Yonekura planted a fifth bomb somewhere in order to kill the last man. The police hurry to identify the fifth man, and Conan and Heiji go to the hospital to see Ishizawa. Later, they learn the identity of the fifth man, but they're unable to find the final bomb planted by Yonekura.
