Fifteen years ago while on a family camping trip, Jakob Shao and his father vanished. His father turned up a few days later, dehydrated and confused, but convinced that they'd been abducted by aliens. Jakob remained missing. The Shao sisters, Kass and Evie, dealt with the disappearance and ensuing fallout in very different ways. Kass over the years stepped up to be the rock of the family. Evie took her father's side, going all in on UFO conspiracy theories. And always looking for Jakob. When atmospheric readings from Evie's network of contacts indicate a disturbance event just like the night of the abduction, she heads back home. Because Jakob is back. He's changed, and the sisters aren't sure what to think. Jakob, Kass and Evie are going to have to grow up and sort out their differences, and fast. Because the FBI is after Jakob, and possibly an entire alien army, too.
