In 2009, five years after the events of Resident Evil 4, Chris Redfield, now an agent of the Bioterrorism Security Assessment Alliance (BSAA), is dispatched to Kijuju in West Africa. He and his new partner Sheva Alomar are tasked with apprehending Ricardo Irving before he can sell a bio-organic weapon (BOW) on the black market. When they arrive, they discover that the locals have been infected by the Las Plagas parasite (those infected are called "Majini") and the BSAA Alpha Team have been killed.
