Albert Wesker
Every game in the series is set in the fictional American metropolitan area Raccoon City until its destruction at the end of "Resident Evil 3: Nemesis". Subsequent games featuring Valentine take place on an international scale: namely Russia, Africa, and the Mediterranean Sea. The original game is set in July 1998 in a mansion on the outskirts of Raccoon City, which Valentine and her team enter into while searching for colleagues. Working with partner Barry Burton, she discovers the property is a façade for a biological warfare laboratory operated by the Umbrella Corporation and its undead occupants are the scientists who developed the T-virus mutagen. Her commander Albert Wesker is revealed to be a double agent for Umbrella. Valentine and Redfield are among the five survivors of the incident, who form a strong friendship and become passionate opponents of bioterrorism.
