A year in the making, but recorded in just one day, The Wargame explores the reality of the threat that Vladimir Putin's Russia could pose to Britain, its people and normal, everyday life.
The Wargame also tests the true state of the UK's defences and national resilience after decades of cost-saving cuts since the collapse of the Soviet Union in 1991.
Assembled a cast of former ministers, military and security chiefs and other experts to play the British and Russian governments.
