Dr. Katō places a bomb on the Neon Lights, the first fully robotic train, which detonates if speed falls below 70 kilometers per hour with passengers aboard. The train’s path leads to the Geoworm energy plant, creating a risk of catastrophe if it does not stop. Atom, a passenger on the train, urgently searches for the device to save everyone. Despite using his latest-model scans, he fails to locate the bomb, leaving the situation critical as the train continues its journey toward the potential disaster.
