Deep in the desert, not too far from infamous Area 51, is a government facility called the Playroom. In this secret facility are a group of six kids, who are not-quite-human. While the Playroom is a refuge for them, it is also an enclosure. A security breach soon propels them into the world––a world dangerous for "irregularities." Before they know it, this group of clever and funny kids is being hunted by employees of the government, UFO conspiracy theorists, and a mysterious and malevolent "Collector."
