Written by the novelist Stephen Gallager , this is the best UK SF drama in a LONG time. Our hero (Jack Davenport - Pirates of the Caribbean ), is a detective for London Metropolitan Police. He is to be best man at the wedding of his partner Jack (Stephen Moyer - True Blood ). However, the night of the Stag do, their informant is murdered. The killer disappears, helped by the fact that he does not appear in photographs, mirrors or on videotape. Neither do his clothes, for some reason.
The groom-to-be disappears, and a group of Government Investigators (including Susannah Harker ) start asking questions about him. The hero has to choose which side he will take.
A blacked-out car is involved in a road-rage incident with a biker (Neil Maskey - Utopia ). The biker smashes one of the car's windows, and the sun's ultraviolet rays cause the driver to burst into flames.
