Holy Loch naval base, all the hostages will be killed. Currie questions Leith's motivations, and Leith responds that her ultimate goal is the total disarmament of the whole world. This opens a debate about method and political philosophy that only antagonises the terrorists. Meanwhile, Dennis and three fellow SAS troopers arrive at Skellen's home. They set up in the attached house next door, using audio and video devices to covertly observe Helga, Mac, and their captives through the wall. Skellen manages to separate himself from the group by feigning a need for the toilet. He uses a shaving mirror to heliograph floodlights and signal Hadley via Morse code, telling him to attack at 10 a.m. while Skellen creates a diversion. Hadley cannot get permission for an SAS attack because the British Home Secretary insists that Powell resolve the situation through negotiation. As the tension mounts inside the residence, a mistake by one of the terrorists causes the death of the SAC C-in-C. This enables Powell and Hadley to get the permission for their assault. The SAS operatives in the house adjoining Skellen's remove a large area of the bricks separating the attached houses. Meanwhile, Helga's temper at the Skellens' crying baby escalates into a fight with Skellen's wife. The operatives work fast to attach a charge to the exposed wall, cut the lights and blow the wall so two SAS soldiers can shoot through the gap, killing both Helga and Mac. As the SAS mount an assault on the residence, the terrorists panic. Skellen overpowers and kills three terrorists. The SAS, deploying from helicopters, force open doors and enter through windows. As they methodically clear the residence, Skellen kills more terrorists including Walker. Skellen joins with Baker and his troop to search for Leith, as the other troopers bundle the hostages to safety. When Skellen hesitates to kill Leith on sight, Major Steele kills her before she can kill Skellen. The Ambassador thanks the troopers as they leave the residence. Skellen and his troop apologise to Hagen and Freund, explain the reason for their actions, and make peace. Skellen departs on one of the helicopters with his colleagues. In a government building, Sir Richard, a politician, complains to a colleague about the violent end to the siege. He then meets the financier Malek, and they discuss future similar actions.
