(Capcom's primary storyline)
The Umbrella Chemical Plant was a chemical manufacturing facility located in the north-eastern industrial zone of Raccoon City, a Midwestern American town. It was owned by Umbrella U.S.A., which had considerable influence on the local economy. The chemical plant was one of the main sources of employment in the city in its final years. The chemical plant also marked the approximate location of the Raccoon City Underground Laboratory, constructed in the early 1990s for G-Virus research.
