COBRA - Episode Guide

A team comprising Britain's leading experts, crisis contingency planners and most senior politicians assembles to help bring society back from the brink of collapse, as the prime minister deals with an unfolding national emergency after catastrophic events throw the nation into darkness. 

With the nation in the full grip of the crisis and experiencing the worst blackout in the history of the UK, Sutherland and his team are forced to work around the clock to restore power. Meanwhile Anna reconnects with Edin, but this dalliance with her past love becomes more dangerous than she anticipates.

Sutherland, Anna and Fraser head to one of the worst affected areas. But while the PM is away, Archie causes problems.

Sutherland's knowledge about his daughter's part in her friend's death is questioned. Meanwhile, a new threat rears its head.

As the nation slides into anarchy, Sutherland considers extreme measures to keep control. Rachel faces tough questions about Ellie.

As his personal life implodes, Sutherland is forced to fight for his political career. Meanwhile, riots rock the nation.

Prime Minister Robert Sutherland, his Chief of Staff Anna Marshall and new Home Secretary Joseph Obasi assemble the emergency committee "COBRA" to respond to a potentially explosive situation in Kent. As the situation in Kent takes a sudden and catastrophic turn for the worse, an unseen enemy chooses this time to strike from the shadows, with devastating consequences.

Following devastation in Kent and the cyber-attack which continues to jam communications, the Prime Minister convenes an emergency COBRA meeting. MI5 Head Eleanor James agrees the timing of the attack suggests Russian involvement, but counsels against inflaming the situation.

COBRA is assembled when fresh disaster strikes - a breach at Dover port means an insidious threat may be in play. As Sutherland is briefed by his team, the mission is set; intercept any trucks which made it through the breach, whilst avoiding mass panic.

Following the latest shocking discovery, the team scramble to understand what it means. It's clearly a message, but who is the sender? Meanwhile, Francine's TV attack on Lord Singer is met with delight by Labour leader Chris Edwards. It is also seized upon by online presence Firestorm, to Francine's discomfort.

Rachel Sutherland is dismayed by the fresh media assault on her reputation, but Robert is distracted - for somehow, Firestorm is back, and spreading misinformation about the water supply. Anna and Eleanor placate the seething PM, but when reports of new cyber attack chimes with Archie's theory that a proxy war is underway, he demands they hit back at Russian and Chinese targets.

Reeling from the events in Kent, the COBRA team are briefed by Eleanor on the nature of a sophisticated malware which has infected the UK's critical infrastructure. An urgent response is needed if they are to avoid total calamity, but with Anna gone and dissent rising amongst the ranks, Robert grapples to make the right decision.

Robert and Anna return to COBRA to try and devise an effective strategy against members of an environmental protest group who are blocking traffic from going through a railway tunnel.

Following the sinkhole collapse, Sutherland and his wife Rachel travel to Godley Common in the hope that their daughter Ellie is still alive. Multiple deaths are reported as rescuers work around the clock to retrieve victims just as news breaks that Shirasian Princess Yadira has been kidnapped and forced back to Shirasia. Meanwhile, Francine Bridge, opposition Minister and a tentative ally of the Planet Resistance movement, is stricken by the disaster and begins questioning her support for what now seems to be a terrorist organisation.

The police interrogate Ellie and Henry, who both deny knowledge of any explosive device, maintaining that Planet Resistance is a peaceful organisation. Knowing his daughter is alive, Sutherland has renewed energy to deal with the aftermath of the sinkhole collapse and the abduction of Princess Yadira.

The government face scrutiny for legislating an aggressive anti-protest bill, leading to police forces going on an unofficial strike.

The government frantically search for a stolen weapon. Dan and his mercenaries demand to be paid a ransom, or the weapon will be used.

Dan breaks into Archie's home, demanding Robert resign from his post or he will use the weapon. Season finale.
