Upon his return to the present, the world as he knows it has changed. And He and Helen are the only one's who know.

As series two opens Claudia Brown has never existed and the others have no idea who she was. Can Nick convince his team that their actions have inadvertently altered the course of nature? But he has absolutely no idea what went wrong or how he can fix it…

Along the way Nick and his team encounter some beastly opponents that find their way through the anomalies.
