This new series returns, and in case you haven't seen it before, no it's not about people who are really good at sex. Well, not really, it's about two pioneering sex researchers in 1950's America who certainly aren't afraid of rattling a few cages with their findings, as Masters discovered at his own expense after his particularly risque presentation in the last series. This opening episode deals with the fallout of that, while Virginia has her own problems to deal with as everyone thinks that she was the woman in the infamous film. Also tonight, Scully comes up with a pretty aggressive way of 'curing' his homosexuality...oh dear.
