London is burning. The politicians have betrayed us. The enemy is already on British soil. When a truck bomb destroys Whitehall, Prime Minister Harry Beecham survives...

Only to learn the attack is the opening strike in a coup designed to conquer Britain. Rescued by the SAS, Harry must escape a chaotic London to reach a secure refuge in the West Country, as political traitors invite Islamic forces onto British soil.

Elsewhere, ex-con Morgan Blake and his neighbour Izzy Gray watch an airliner fall from the sky over west London. With streets descending into violence and panic, Morgan activates a desperate plan to escape the capital - a plan that becomes a brutal test of courage, instinct, and trust.

As an invading army gathers on the Scottish border, British troops dig in for the final, brutal fight—but Harry Beecham has one last, desperate plan—one that could either reclaim a nation or finish it forever.
