For several days, the Black Organization has been killing FBI agents. Conan and the FBI deduce that the Organization must be deciphering the FBI's coded messages, so they decide to use it against them by laying a trap for them. Supposedly dead Camel and Mark, the older brother of a killed agent, are chosen to go to the meeting location. However, no one arrives at the location indicated by the code, and shots are fired on the agents keeping watch. Will Camel be able to evade the Black Organization without them realizing he's still alive?!
