People keep collapsing everywhere. 20,000 humans die of unknown causes. Since radioactivity has been detected at the same time, the Science Ninja Team starts searching for its source. While investigating, Jinpei and Ryu encounter three boys and go with them to the Negiris plateau. The boys love UFOs and wanted to try to establish a contact with the extraterrestrials. They say they caught some strange radio waves while doing so. Following its source, Jinpei, Ryu and the boys arrive at Stonehenge. At that moment, a solarshifter appears out of the Stonehenge stones and Jinpei and the boys are taken away. Ryu is left behind. He meets up with Ken and the others. They want to save Jinpei, but can't approach because of a strong barrier in form of a dome. Elsewhere, Jinpei has heard the whole secret of the base. He tricks Gel Sadra, taking advantage of her way of thinking, and escapes the holding cell, taking the solarshifter's programming chip with him.
