In the far north of Canada sits Camp Zero, an American building project hiding many secrets. Desperate to help her climate-displaced Korean immigrant mother, Rose agrees to travel to Camp Zero and spy on its architect in exchange for housing. She arrives at the same time as another newcomer, a college professor named Grant who is determined to flee his wealthy family's dark legacy. Gradually, they realize that there is more to the architect than previously thought, and a disturbing mystery lurks beneath the surface of the camp. At the same time, rumors abound of an elite group of women soldiers living and working at a nearby Cold War-era climate research station. What are they doing there? And who is leading them?
