Story without spoilers

Fourteen days before the main events, a comet crosses the sky and releases parasitic spores called Gray Matters. The infection spreads quickly, turning people into savage monsters and causing society to collapse. Authorities isolate affected cities, conceal the truth and abandon the outbreak zones.

Mai breaks into Central Hospital, identified as the origin point of the outbreak, because she does not accept the government’s account. With BooBoo alongside her, she rescues a young girl named Anna and attempts to get out of the hospital alive. Their escape is complicated by Ren Cade, a ruthless black-ops commander pursuing Mai, and Dr. Theodore, who directs events from mission control. Theodore also deploys Ares, a genetically engineered killing machine created specifically to eliminate Mai.
