In a futuristic Great Britain, the last remnants of human civilization live in a massive domed city.  Here, society thrives under strict control, where no one lives beyond the age of 30, and "Commencement" promises a renewed life for all citizens.  But the reality is far darker:  those who reach their time must face death.  The Icemen, including John-6-Steed, ensure that no one escapes their fate.  

Steed, once a loyal Iceman, begins to question the system. Joined by Tara-7-King, the two find themselves on the run from the very society they once protected.  Fleeing the city, they venture into the ruins of ancient London, now buried under the wastes. Pursued relentlessly by his former partner, Emma-8-Peel, who still serves as an Iceman, Steed, Tara at his side, discovers unsettling truths about their world and the true purpose of Commencement.

This story is a blend of the stylish espionage of The Avengers with the dystopian themes of Logan's Run, as Steed and Tara race against time to find Sanctuary---if it even exists.
