In a world stretched far and wide, citizens live under domes led by specially trained Meteorologists and monitored by Bureaucrats after a calamitous meteorite killed millions of citizens …
That was over a hundred years ago. Now life under dome is fine, orderly, and especially so under Dome 224 led by Meteorologist Hubert Shaffer. But a serene life is always under threat from the outside, and after Dome 224 is cracked by a meteorite fragment, Hubert and his meteorological assistant Moe (with his loyal pet rock) must brave an exterior journey to the almighty Bureaucratic Dome for aid.
And they are not going alone. Seizing her opportunity inspired by Bureaucratic-approved literature meant to scare children from outside the dome, an ambitious girl named Mazie wedges her way into the journey, forcing her fearful mother along as a guardian.
These four (with their pet rock) must band together to brave the elements, animals, and the alien outdoors to rescue their fellow domers. But the world outside is much more terrifying than any of them could imagine.
