Resident Evil 5 Plot 1-3

Five years after the events of Resident Evil 4 Chris Redfield, a former Special Tactics and Rescue Service member and now part of the Bioterrorism Security Assessment Alliance (BSAA), is dispatched to Kijuju in Africa. He and his new partner Sheva Alomar are tasked with apprehend 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 parasites (those infected are called "Majini") and the BSAA Alpha Team have been killed. Chris and Sheva are rescued by BSAA's Delta Team, which includes Sheva's mentor Josh Stone. In Josh's data Chris sees a photograph of Jill Valentine, his old partner, who is presumed dead after a confrontation with Albert Wesker. Chris, Sheva and Delta Team close in on Irving, but he escapes with the aid of a hooded figure. Wesker leaves documents which lead Chris and Sheva to marshy oilfields where Irving's deal is to occur, but they discover that the documents are a diversion. When Chris and Sheva try to regroup with Delta Team, they find the team slaughtered by a BOW; Sheva cannot find Josh among the dead. Determined to learn if Jill is still alive, Chris does not report to headquarters.
