Episode 4
45min - Nick may be with his family but he still reels from the illness. He has nightmares and struggles to adjust to life post-Novichok. He and his wife Sarah hear that not only have they lost their home and everything in it, but that they will not be receiving a pay-out from the insurance company—acts of international terrorism are not included in the policy. When Nick hears about Charlie and Dawn he falls deeper into depression, afraid he might be the reason they are ill. Tracy learns that the contamination radius might be even bigger than last time, realizing the second poisoning outbreak is much worse than the first—this time the discovery of the poison is entirely random and no one is safe. The poisoning proves fatal for Dawn. Her family is left to mourn her sudden death and are immediately pursued by the tabloid press and forced secretly to flee to a different city. Her father becomes fixated on finding out the truth about what has happened. Afterwards, it looks like this second chemical contagion has again been contained. None of them will ever forget the Salisbury poisonings but the city is once again safe.
