Drexill is using human guinea pigs for his experiments on sensory deprivation. Meanwhile, Anne travels to Paris to the Mayer Institute to take part in a study of sensory deprivation.
I've always thought there is something wonderfully nasty and dark about this episode, the way Drexill uses his powers on the male victim, regressing him, and then on Anne, very dark. The way they manipulate Anne's senses and awareness is also very nasty.
Looks like they invented wireless headphones much earlier then expected.
Cyril Luckham is seriously creepy as Drexill once again, and Bruce Boa is really good as Masson too.
More questions are asked, as Drexill explained that he had someone to answer to also.
This is an excellent episode, one of the best I think, definitely one of the most memorable, 8/10
