An unexploded bomb, mistakenly thought to be from WWII, is discovered on a busy construction site in
Paddington. As the military and police, under the command of Chief Superintendent Zuzana Greenfield, cordon off the area and evacuate civilians, including Rahim and his parents, to
Hyde Park, Major Will Tranter and his team are sent in to try to defuse the bomb. The operation is complicated when Tranter discovers a timed trigger. One of the soldiers uses a magnetic device to temporarily disable the timer, while the rest attempt to build a wall to contain and soften the blast. Amidst the chaos, Karalis, X, Y and Z break into a bank in
Edgware Road by drilling underneath, and steal money and jewellery. Their heat signature is spotted from Rahim's apartment by a police drone, suspending the bomb disposal operation while policemen search the cordoned area. Karalis is spotted, and the police engage in a chase with the robbers. The device malfunctions, reactivating the timer and eventually resulting in the bomb detonating before the wall can be completed, but no lives are lost. The robbers manage to evade the police and escape in a van to a safehouse in the countryside. There, Karalis reveals uncut diamonds among the loot, then double-crosses them by calling in a team of armed gangsters he works for, who tie up the robbers and leave them locked in a shed. When Karalis discovers the diamonds are fake, the gangsters break his hand, lock him in the boot of their car and drive off with him, but he is able to use his phone to broadcast his location. X, Y and Z escape the shed and, already tracking him, catch up, kill the gunmen, and attempt to suffocate Karalis, but Tranter arrives and shoots X dead, allowing Karalis to escape. The police finds out the bomb is actually from the British Army, but by the time they are able to figure out Tranter, Karalis and Rahim's involvement in the heist, the three have fled the UK on separate flights. Reuniting in Istanbul, it is revealed that Tranter was working with Karalis to steal the diamonds; when Karalis was discovered, Tranter sabotaged the device, triggering the explosion to buy them time to escape the police. After arranging for the diamonds to be cut and sold, and dividing the money equally between them, the three part ways. A flashback reveals that Tranter, Karalis and Rahim first met ten years earlier in Afghanistan, when Karalis was double-crossed by his employer, who kidnapped him, only for their convoy to be caught up in an IED blast; with Tranter and Rahim providing cover fire, Karalis was able to disarm most of the remaining land mines. == Cast ==
