In resident evil 4, special agent Leon S. Kennedy is sent on a mission to rescue the U.S. President's daughter who has been kidnapped. Finding his way to a rural village in Europe, he faces new threats that are a departure from the traditional lumbering zombie enemies of the earlier instalments in the series. Leon battles horrific new creatures infested by a new threat called Las Plagas and faces off against an aggressive group of enemies including mind-controlled villagers that are tied to Los Illuminados, the mysterious cult which is behind the abduction.
