The spy game is a serious business, and throughout history, the tools and technologies developed for it have mattered as much as the spies themselves. A Non fiction series about the tools of the trade and the different ways countries have spied on each other and gathered intelligence over the decades. Different methods are examined in each episode, from poisoning enemies to "sexpionage" to good old covert operations. The series paints the picture of how intelligence-gathering has changed in a lot of ways over the years, but in many ways is done the same way it's always been done. Based upon the book by Henry R. Schlesinger.

As long as there has been espionage, sex and the promise of it have been powerful tools of persuasion and blackmail.

Special operations require skillful people, but some of the most famous missions in modern history relied on elite technology.

Espionage experts reveal how spies obtain sensitive intelligence about foreign entities through clandestine collection, and also, how they use covert systems that are secure from enemy interception to communicate with their handlers.

For some covert missions, assassination is the goal, and lethal toxins are deployed by spy agencies to kill perceived foes.
