The Torasshuu power plant provides electrical power to the city of Utoland. Nambu charges its head, Dr. Komibe, with the testing whether a space capsule is fireproof or not. A test which requires the highly powerful incinerator of the plant. That evening, Ken and the others come to the station to say goodbye to Ryu, who is boarding the night train because his father is in critical condition. However, while Joe is heading towards the station, he hits a child and brings it and its mother, to the hospital. During a testflight for the mecha Angler, Katse lands by the power plant and forces them to recharge the mecha. This causes a blackout in the city. As a result, Ryu expects the re-establishment of power supply in the middle of the train, Joe in the hospital, where they are in the middle of the operation, the other three in a restaurant. But Ken and the others get suspicous at the length of the blackout. They go to the power plant. Katse, disguised as Komibe, throws the three of them into the incinerator and installs a pendant bomb inside the plant. The incinerator is fired up, but by fleeing into the capsule left by Nambu, they escape from the danger. They defeat the Galactor members who come to check on the situation. Jun then plans, with the help of Komibe, the re-establishment of the power supply and Ken attaches the pendant bomb discovered by Jinpei to his boomerang and throws it after the fleeing mecha. When Katse wants to blow up the power plant and presses the button, the mecha itself explodes. The power comes back to Utoland City. Ryu learns on the phone in the train that his father has overcome the critical condition. In the hospital, Joe is relieved by the fact that the operation on the child was a success.
