Carmen, Walker's wife, is a scientific lecturer at the nearby University, and she stumbles upon a possible cause of the criminal's deaths. Armed with this knowledge, the Walkers attempt to visit their friends but find the Keyes' have disappeared. Eventually, Walker begins to forget the whole matter until certain occurrences take place, and these point to the Retribution Committee still being very much active.
