Hidden

Episode 4

In the aftermath of the shootout in Kent, Frank Hanna lies injured. Unable to alert the police to what's happened, Harry and Gina drop him at a hospital and head to see Joe Collins in a hotel room near Heathrow. Collins is in a desperate state. He tells them he was hired to do a job for Styles a while back but changed his mind. However, rather than walk away, he made the fatal mistake of stealing his laptop. Realising its contents probably hold the answers, Harry takes the laptop and heads to Lauren's with Gina. In the morning, the two of them split up: Gina goes to Nigel Fountain for answers, while Harry finds someone to break into the laptop. Both trips deliver some unexpected truths, and Harry suddenly realises he has less than an hour to stop an event that could change everything – not just for himself but for the country. In a climactic showdown, he is forced to confront the past that has long haunted him.
