Trioxin is a chemical compound that reanimates dead bodies by restoring basic motor functions and hunger instincts. When people breathe the gas, it causes symptoms like disorientation and physical deterioration, eventually leading them to transform into mindless, flesh-eating zombies who attack the living.

Foreshadowing: The dead bodies in the cemetery begin reanimating before any living characters show symptoms, indicating the gas affects the deceased first.
