Only a scant handful of highly placed people were aware that the German Nazi were in the process of developing an atomic bomb before the outbreak of WWII. A small group of agents recruited by British Naval Intelligence sets out to stop or at least slow down the development of the bomb and the missiles that would launch the deadly explosive that would vaporize London.

Not willing to pass their down time standing by idly, the band of assassins and saboteurs used every opportunity to disrupt the Nazi war effort. From 1938 to D Day, the Team operated undercover, fighting to keep the efforts of the Abwehr and the Gestapo at arm's length the entire time.

Failure didn't mean just capture, it meant vicious torture and excruciating painful death for the Team and absolute destruction for all of the United Kingdom. And-without doubt-the rest of the world.
