Resident Evil 5 (2009)
"Resident Evil 5" takes place five years after the events of "Resident Evil 4," Chris Redfield, a former S.T.A.R.S member and now part of the Bioterrorism Security Assessment Alliance (BSAA), is dispatched to Kijuju, Africa to work with Sheva Alomar to apprehend Ricardo Irving before he can sell a bio-organic weapon (BOW) on the black market. Upon arriving, they discover the locals have been converted by parasites into Majini, and that the members of the BSAA's Alpha team have been killed. Chris and Sheva are rescued by BSAA's Delta team, whose membership includes Sheva's mentor Josh Stone.
In the data provided by Josh, Chris sees a photograph of Jill Valentine, his old partner, presumed dead after a confrontation with Albert Wesker. Chris, Sheva, and Delta team close in on Irving, but he manages to escape with the help of a hooded figure, leaving behind documents that lead Chris and Sheva to oil fields in the marshlands where Irving's deal is to occur. They soon discover this was a diversion created by Irving to allow the deal to take place. Chris and Sheva attempt to regroup with Delta team, but at the rendezvous, find the team slaughtered by a BOW; Sheva cannot find Josh among the bodies. Chris refuses to report to headquarters, revealing his determination to learn if Jill is still alive.
Continuing through the marshlands, they find Josh injured but safe, and with his help track down Irving's boat. Irving injects himself with a variant of the parasite, Las Plagas, and mutates into a colossal octopus-like beast. Chris and Sheva defeat him, and with his dying words, directs the pair to a nearby cave to learn more. The cave, home of the Ndipaya tribe, is the source of the flower used to create the Progenitor virus, which led to the creation of the T- and G-viruses, and has now been used to form a new, incredibly powerful strain called Uroboros. Chris and Sheva find evidence that Tricell, the company funding the BSAA, had taken over a former Umbrella underground laboratory and continued Umbrella's research. ...
