A diabolical plot hatched by General Irfan Akram, who has seized power in a bloody coup in Islamabad, to assassinate US Secretary of State Barbara Evans during an official visit to Pakistan, goes haywire when the fidayeen squad tasked with the assassination turns rogue, and acquires a tactical nuclear weapon outside the knowledge and control of its handlers in the ISI.

Then, when further intel reaches the US of the nuclear weapon in the fidayeens' possession, an incensed President Alan Wilkins threatens the Pakistanis with nuclear annihilation. In pursuance of this, he orders Carrier Strike Group Three into the Arabian Sea, and positions it two hundred nautical miles off Karachi Harbour... Panic grips the Pakistani Army and the ISI when the realisation sets in that they are unable to establish contact with their fidayeen squad, and the top leaders of the al-Qaeda, the Lashkar, the Haqqani Network and the Tehreek-e-Taliban-e-Pakistan, who have been involved in creating and nurturing the fidayeen squad, have suddenly turned incommunicado, and are untraceable.
