A month and a half has passed since the incident. September has come to Raccoon City, a small industrial city in the American Midwest. People are starting to forget the chaos at the mansion as their lives return to normal.
The bizarre incident that occurred in the Arclay Mountains, the destruction of the special taskforce S.T.A.R.S., Umbrella's secret biological weapons laboratory hidden in an old mansion, the power of the T-Virus that turns humans and animals into horrible monsters... how could it all happen here?
People could not believe the survivors' reports. Stories of their incredible experiences and of strange biological weapons and zombies were beyond the townsfolks' imagination. The surviving S.T.A.R.S. team members headed to Europe even before the town heard the full details of what had happened.
They hoped it was all over. But then it happened again. Suddenly a series of inexplicable murders occurred and a strange disease began invading neighborhoods. T-Virus was flowing into the city...
The invisible plague snuck up silently and turned the unsuspecting citizens into monsters. People cursed their foolishness, but the nightmare had already begun. The future was out of their control.
Raccoon City was on the brink of collapse...
