It's 1998. The special forces division S.T.A.R.S. sends out Bravo team to investigate bizarre murders on the outskirts of Raccoon City. They soon lose contact with the team.
Soon after, Alpha team is sent to search for Bravo team. They soon find themselves in the middle of an eerily quiet wood. There they discover the wreck of Bravo team's helicopter. The pilot is already dead.
While Alpha team search for the other members, the silence of the wood is broken by a pack of strange, disfigured dogs, which attack in a bloodthirsty rage. The dogs kill one comrade and the surviving team members run for their lives with the pack of hungry hounds chasing at their heels.
Struggling to catch their breath, the team notices a mansion close by and quickly make their way inside. The mansion saved them from the dogs, but who's going to save them from the mansion?
