The last in a line of secret military facilities set up by the British Government.

The project had been the brainchild of Winston Churchill who, at the time of Britain's bleakest hour in World War Two, ordered what is known now as the War Rooms constructed behind Whitehall. 

After Churchill loses re-election in 1945, the following Government shelves plans for a successor to the war rooms and they were subsequently sealed-up but not forgotten. When Churchill is re-elected early in the following decade, work began on the secret project below the streets of Whitehall - the original Bulldog One base - but Churchill is not done yet.

As the Cold War gets more unpredictable, Churchill orders construction of a second base in the Midlands. A third base follows in Cornwall before an ambitious fourth base is constructed under a North Sea oil rig.

As an after thought, the Western Isles also have a base constructed underneath the Isle of North Uist. Here, as successive governments came and went, expansion is started but never finished properly and when it comes to personnel, manpower is always limited.

Bulldog Five, a base supposed to house 3000 people in a time of war is unexpectedly assigned to Major Morgan, a disgraced Marine who has been exiled to St. Kilda.

As he arrives at Bulldog Five, he is welcomed into the base by the civilian administrator - Doctor Jennifer Morris and Morgan quickly appoints her his second in command. A command that has barely over 600 people - civilian and military - with not a hint of a medical team being provided either.

Adding to his woes are an undisciplined gaggle of US Rangers he inherits, led by a drunken Captain along with a less than welcome VIP, the uncle of the King, a Prince who he'd rather not see, ever.
