In most of its titles, Zombies are enemies but Resident Evil 4, also known as Biohazard 4, done it differently. Biohazard 4 features villagers, infected by the mind controlling parasite known as Las Plagas, who committed their lives to the cult named Los Illuminados.
A special U.S government agent, Leon S. Kennedy, is sent on the mission to investigate the abduction of President’s daughter where he travels through the several areas of nameless Spanish village and encounter villagers who were infected by the parasite. Later, Leon found himself captured by the villager’s chief and met a researcher, Luis Sera, and they both work together to escape but soon they separate their ways.
