In the last ever series of acclaimed spy drama Spooks, the team has been left reeling by Lucas North's betrayal, and with Harry Pearce on gardening leave, Section D has a new leader. Erin Watts is acting head and she has brought Calum Reed with her, a brilliant officer and technical genius. However, Harry Pearce survives his MI5 employment tribunal and is quickly back on the Grid in the thick of the action. Buried secrets are unearthed when Max Witt, a retired spy and Harry's colleague in Berlin during the Cold War, is found murdered by an unknown assassin. Meanwhile Ilya Gavrik, Russia's foreign ambassador and Harry's opposite number in the KGB for much of the Eighties, has flown into London to negotiate a ground-breaking strategic partnership between Russia and the UK. Peter Firth heads the cast, co-starring Lara Pulver, Geoffrey Streatfeild, Jonathan Hyde, Alice Krige and Simon Russell Beale.
