1990 - Season 1 Episode 7 Witness

Dr. Alan Vickers, whom Kyle and Breet helped escape, has been campaigning throughout the United States to get public and world opinion to force the PCD to let his wife and daughter emigrate. The problem is that in his speeches he may have let clues drop that may lead Skardon and the PCD to Kyle. When the PCD go after Kyle's family and a plot to frame Kyle blows up in the PCD's face, Delly Lomas goes to America to persuade Dr. Vickers to return to England to testify against Kyle in return for exit visas for his wife and daughter.
