Kagaku Ninja-tai Gatchaman

Synopsis

In the country Inderia, droughts and heavy rainfalls occur every year. In cooperation with the ISO, a plan to build a dam in the hinterland to create lots of arable land is being made. But through mysterious events which are happening again and again around a shrine which will be inundated by the dam, the plan is only progressing very slowly. At long last, the Torakodon skeleton appears.

The Science Ninja Team gets the order to investigate and sneaks into the country. Events like a landing transport plane exploding on the runway the God Phoenix was supposed to use, show the handwriting of Galactor. Jinpei and Ryu, staying in a cheap hotel, get involved in a murder case.

Ken hears that the murder might have been connected to the fact that a golden coin has been found at the construction place. He thinks that the picture carved into the coin shows a secret underground passageway to the shrine and starts to investigate that shrine.

While escaping, Ryu and Jinpei sneak into a Galactor base built in the cellar of the shrine and learn that the purpose of Torakodon is to have people stay away from the missile construction plans in that base. Ken and the other sneak in from the street and together they destroy the missiles. They blow up the control mechanism for Torakodon and defeat the Galactor members. Afterwards, they leave the rest to the local police and depart from the country.

Then, just as Katse arrives in Inderia, the base explodes before his eyes.
