All 10 episodes from the fifth series of the BBC's political espionage drama following a team of officers in MI5. As the series begins, Adam (Rupert Penry-Jones), recovering in hospital, hears that the country is falling apart. A terror attack on a gas and oil depot has led to energy rationing and people are dying of cold. The media are blaming weak leadership and one media group in particular is peddling anti-government propaganda. Galvanised by these events, Adam discharges himself from hospital and returns to work. Meanwhile, Ruth (Nicola Walker) is framed for murder as part of an elaborate cover-up involving the torture of a terrorist group. In the climatic finale, environmental terrorist group 'Divine Earth' storm the Thames Barrier and threaten to flood London if the government doesn't publish a secret document entitled 'Aftermath', which supposedly outlines plans to scrap pollution cuts and instead focus on securing the remaining resources for UK and US consumption.
