A bomb detonates and kills an unknown man. On the other side of town, Ayumi's neighbour Mao runs to the Detective Boys for help with her runaway dog, Candy. While searching one of the nearby delivery trucks, they bump into Takagi and Chiba working a serial bombing case. The police locate the last bomb in a delivery truck, but it is then hijacked by two robbers. Candy happens to be in that truck. The police leak fake checkpoints and corner the robbers. Conan manages to jump into the truck and convince the robbers to drive somewhere open to throw out the bomb saving everyone.
