Nick in “Unfinished Business”

Nick

(voiceover) My name is Professor Nick Cutter. Eight years ago, my wife, Helen, disappeared. I discovered she had stepped into the past through ruptures in time called 'Anomalies'. Now creatures from the past threaten the future of the human race. There's only a small group of people who know the truth. My research team: Stephen Hart, Connor Temple, and Abby Maitland, and Government officials James Lester, and Claudia Brown. I returned from the past to find that something has gone terribly wrong, and Claudia Brown has vanished, as though she was never even born. I've come back to a different world, and Helen and I are the only two people who know it.
