Steed and Mrs. Peel

Steed and Mrs. Peel was a 2012 American comic book series published by Boom! Studios and featuring characters from the 1961 British television series The Avengers.

A Very Civil Armageddon (Volume 1)
In an underground bunker, John Steed, Mrs. Emma Peel, and a host of important generals and members of Parliament watch in horror as nuclear missiles destroy London. Forced to the surface by a bunker fire, the survivors fall in with the notorious Hellfire Club, who built their own luxurious underground quarters in advance of the nuclear armageddon. Steed and Emma begin to notice that not everything adds up about their situation- clouds seem to move in the wrong direction, and everyone seems to have eaten the exact same breakfast on the morning of Doomsday. Moreover, some of the generals and MPs have started to go missing.

Steed discovers that Ian and Joan Cartney (the children of former Hellfire Club head John Cartney) are brainwashing the government officials. He is confronted by Mrs. Peel, who has been brainwashed into becoming the Hellfire Club's "Queen of Sin." Luckily, Steed and Emma have given themselves a series of post-hypnotic suggestions that they can use to break each other's programming if need be, and Steed is able to quickly free Emma from the Club's control.

Steed and Emma flee the bunker into the wasteland, but they reveal that they have already figured out the truth- the "wasteland" is simply a movie set on an island in the South China Sea. Their memories of having breakfast and then being ushered into the bunker were implanted by the Carneys, and the nuclear war itself never happened. The Royal Navy, summoned by the agents, arrives to put an end to the scheme.
