The episode opened up at the Thames Estuary in Kent (actually filmed in Fleetwood, Lancashire). Fraser Walker (Richard Dormer) and Audrey Hemmings (Alexa Davies) were overseeing the evacuation of the town and examination of an off-shore wreck from World War II. Earthquake tremors were threatening to disturb the wreck’s potentially explosive cargo.
As another tremor struck, the action jumped back to 24 hours earlier. At Downing Street, Sutherland called a COBRA meeting to discuss the tremors in Kent. Joining the meeting for the first time was new Home Secretary, Joeseph Obasi (Richard Pepple). Fraser briefed the room on the situation in Kent and explained that they didn’t know if the wreck would explode or not. If it did it could reshape the coastline and cause a large loss of life.
Meanwhile, near Twickenham Stadium, an armed drone was used to shoot down a helicopter. The target of the drone was a Ukrainian Oligarch who was aboard. The crash also killed a rugby coach. Eleanor James (Lisa Palfrey) briefed Sutherland on the incident and his options. An investigation uncovered that the hit was carried out by the Russians. This led Sutherland to a dilemma as the assassins could be arrested but doing so might lead to repercussions. He decided he couldn’t let them flee and had them arrested at the airport.
Back in Kent, the tremors caused the ammunition on the wreck to explode. This sent a devastating tsunami towards the shore. Hemmings was injured and knocked from a boat into the sea, while Fraser tried to escape the area by car. He found himself trapped in the floodwaters but eventually managed to get himself free.
At the end of the episode, as COBRA tried to survey the damage their communications went down. A cyber attack from an unknown enemy had spread malware through their systems. The message ‘Ruin Britannia’ appeared across their monitor screens. Sutherland demanded answers.
