Just watched the first episode of this and it’s pretty decent. Deals with a literal National Socialist movement in 1962 London and a Jewish anti-fascist group sending people into it as undercover agents, including our heroine Vivien “Evans” (but really Epstein) from Manchester who goes to London looking for her lost love, only to learn what he’s really up to (infiltrating the neo-Nazis).
I had no idea the neo-Nazis were this brazen in Britain that soon after the war. In one of the scenes it looks like they actually incorporated some footage of a real near-riot that broke out at an event of the NSM in 1962 between their adherents and opponents.
Here’s a trailer:
