The Umbrella Corporation is the most powerful and influential commercial entity in the world. It holds its public dealings in medicine and health care. Secretly however, it holds its goldmine in military applications and bioweaponry.
Beneath Raccoon City is a secret underground lab, The Hive, owned by Umbrella for viral research and development. After a viral weapon known as the T-virus escapes into the air vents and infects the scientists working there, the Red Queen, a massive supercomputer running all electronic units in the Hive, seals them in and eradicates everyone to keep the virus from spreading.
Five hours later, Umbrella's biohazard team arrives to shut the Red Queen down and escape with their lives.
