In the continuing Planet X91 series the drought, Clay, Florian, and Josh ride their horses into the forest. They must launch a small rock packed full of synthetic ice crystals into a cloud so it can rain and break the drought. When they stop for a rest they are cornered by a large prehistoric spider. Just as they fight to live a human girl, Briana, saves them. Josh is the only one who suspects something isn't on the level. When Evelina, a teenager the same age as Clay crashes what appears to be a small space shuttle she was piloting, Clay seems to fall into a love trance. Josh suspects the newly constructed camp isn't what it seems and sets out to prove he's correct. The trio is more than welcome to enter the camp. Only thing wrong, they can never leave. It's up to Josh once again to save the trio from certain death. To do this he sets a bomb to blow up the alien spaceship. He soon discovers the rescue didn't work the first time around.
