E73: “The Workers' Institute” - Aravindan Balakrishnan

His communist cult was started in 1974 in hopes of convincing working class citizens of England to rise up against their capitalist overlords and join forces with communist China. After two "members" escaped in 2013, it was revealed Aravindan Balakrishnan was enslaving women in the basement of his London flat. One woman born into the cult never had contact with the outside world before her release.
