British Intelligence has invented a method for identifying traitors within the security services using Big Data and Artificial Intelligence.

This method is perfect, except for one big problem – it can’t tell the difference between a traitor and an adulterer. Spies are not the most faithful of people, so it’s difficult to separate the true backstabbers from the mere shaggers.

Despite this limitation, the method successfully identifies some double agents. The Russians react by shooting up a central London bookshop to destroy the team responsible for the method. After the shooting, the team regroups and relocates to the truly awful English seaside town of Blackpool to set up shop in its ridiculous Tower. They believe this is the last place the Russians would think of looking for them.

The race is now on to perfect the method and to identify any remaining traitors, while staying one step ahead of a Russian assassination squad.
