Biohazard 4: Incubate

Several years after the disaster in Raccoon City, U.S. government agent Leon S. Kennedy receives an extremely important assignment. The President's daughter, Ashley Graham, has been kidnapped by unknown persons, and the kidnappers' trail leads to a remote region of Spain. Arriving on site, Leon discovers a strange village whose inhabitants behave extremely aggressively and attack any outsider. It soon becomes clear that their behavior is caused by the Las Plagas parasite, which can bend its hosts to another's will. Once he finds Ashley, the agent realizes that the rescue operation is only just beginning.

The attempt to leave the dangerous territory turns into a nonstop struggle for survival. The two must hide from armed fanatics, fight off infected enemies and search for ways out of countless traps. The trail of the conspiracy leads them to an ancient castle, a network of underground catacombs and secret research facilities where dangerous experiments were conducted. Gradually the activities of the Los Illuminados cult come to light, a cult that seeks to use the parasites to achieve its own ends.
