A bizarre incident occured in the outskirts of an American suburb called Raccoon City.
It was later revealed that the terrible disaster had been caused by the t-virus: a mutagenic toxin created by the international enterprise Umbrella, Incorporated for use in bio-weapon experiments. The Raccoon City Police Department’s special S.T.A.R.S. unit immediately began an investigation in the affair. The case was apparently closed thanks to the efforts of S.T.A.R.S. members Chris Redfield and Jill Valentine.
But the Umbrella Corporation’s experiments were far from finished."
