A remote mountain community is suddenly beseiged by a rash of grisly murders encroaching upon it from the surrounding forest. Bizarre reports start to spread, describing attacks from viscious creatures, some human...some not. At the centre of these deaths is a dark, secluded mansion belonging to the mysterious Umbrella Corporation. For years Umbrella has laboured within the mansion, unwatched, ostensibly conducting benign genetic research. Deployed to investigate the strange goings on is the Special Tactics and Rescue Squad (S.T.A.R.S), a paramilitary response unit boasting an unusual array of mission specialists. They believe they are ready for anything but nothing prepares them for the terror which awaits them when they penetrate the mansions long-locked doors. Behind the horror of nightmare creatures, results of forbidden experiments gone disasterously wrong, lies a conspiracy so vast in its scope and so insidious in its agenda that the S.T.A.R.S will be betrayed from within to ensure that the world never learns Umbrella's secret. And if any survive...they may well come to envy those who do not.
