A nuclear leak that was covered up, a breeze carrying death. When radioactive dust quietly drifted toward the town of Anning on the border of Country C, environmental monitor Wu Qingqing was the first to sound the alarm.

Truth and lies, life and interests, an evacuation operation in a race against death, unfolds in a race against time!
