In 1960s London, Vivien, a young Jewish hairdresser, discovers the 62 Group – an intelligence-gathering underground movement trying to stop the rise of the far right.

Vivien meets Colin Jordan, who takes her into the heart of the National Socialist Movement. She takes a huge risk but manages to find out what happened to Jack.

Vivien is introduced to Colin Jordan's wife, dedicated Nazi occultist Francoise Dior. The fascists plan a deadly attack, and the 62 Group do everything they can and stop them.
