Freda's mother - Aunt Martha - was a dedicated Nazi before and during the war and suspected of being in Hitler's bunker on the day he died.

Taking advantage of the chaos she, her followers and a number of gifted scientists absconded to a secret redoubt prepared for the Fuhrer's use where they have been ever since.

Various scientific breakthroughs have given her cloning for her doubles, flying saucers for transport and the ability to control the satellite nuclear weapons of other nations.

Many of the doubles are unhappy with their isolation, and want the freedom of the outside world - some have gone so far as to create lives for themselves while off-base, and a few have refused to return at the end of assignments.

Freda discovers underlying resentment between the male and female doubles, with occasional skirmishes between the two genders slowly escalating.

Johnny muses that little has changed as the base still exists, as does the technology for cloning, and he can still expect a "plan for chaos" at some point in the future.
