Episode 6

In the final episode of the acclaimed conspiracy drama, the gang are holed up in a disused hospital wing, where Arby (Neil Maskell) is recovering from his wounds, protected by Jessica (Fiona O'Shaughnessy). For Ian (Nathan Stewart-Jarrett) and Becky (Alexandra Roach) the race is on to find out who is going to release the flu. They track down Dobri Gorski in a police cell, where he tells them the names of the three people he trained to release the flu. A process of elimination leaves them with Terrence, but they still have to find him. With Milner dead, Wilson (Adeel Akhtar) is alongside them, but his new ruthlessness is unnerving - can they trust him? Meanwhile, Becky is fast running out of Thoraxin, and makes a drastic decision.
