Her mission shifts when she rescues a young girl, Sherry Birkin, and becomes her protector. Claire battles through the police station and underground labs, pursued by Sherry's monstrous, G-virus mutated father, William Birkin, and the corrupt Chief Irons. Her story is a parallel campaign to Leon's, defined by her maternal instinct and determination to survive and get Sherry to safety.
