1x48 - Science Ninja Team Gatchaman

Galactor plans to use the Shutterkiller to copy data from ISO institutions and to then destroy those institutions. The ISO institutions are attacked one after the other. The Science Ninja Team guards the institution which is most likely to be attacked next and, shortly pretending to have been defeated, follows the mecha in the G-4. Jinpei finds the Galactor base in the middle of the desert and goes on digging into the earth with his G-4. In addition, the other four team members follow him and sneak in. But when they enter the base, the G-4 machine is left unmanned. They start looking for Jinpei, and find a factory which restores the copied ISO data. Splitting up, they continue with destroying the factory and looking for Jinpei. Meanwhile, Jinpei has been taken along by a spaceship which is supposed to transmit rays from the mecha. Jinpei is saved and the factory destroyed, but Katse gets in the mecha and escapes. Attaching a wire to the mecha, Ken and the others follow him. Katse wants to shoot at them with the mecha's electronic laser flash. Ken notices this and throws his boomerang into the shutter part of the mecha. As a consequence, the mecha can't open the shutter and the laser hits its own interior. The mecha blows itself up. With a damaged hull, the Science Ninja Team returns to its base. But Katse will be back, showing his teeth.
