Watch: First Trailer For 'Masters Of Sex' Season 2 Starring Lizzy Caplan & Michael Sheen

nullOne of our 20 Best TV Shows Of The 2013/2014 Season, Showtime‘s "Masters Of Sex," is certainly one of the most intriguing dramas going on television right now. While the premise could easily have been pushed in a tawdry direction, the first season turned out to be something far richer, with Michael Sheen and Lizzy Caplan leading an array of complex characters, with varying relationships and attitudes to sex. And it says something about how much consideration is given to the supporting characters that Allison Janney got one of the most moving and heartbreaking arcs of the entire first season. And so, needless to say, we’re stoked for season two.

And the first trailer is here and things are getting even trickier for Dr. Bill Masters. It would appear his relationship with Virginia will continue, even if it means spurning his wife, and putting his professional career in jeopardy. Oh hey look, there’s Danny Huston in what looks like a substantial guest spot too. Where does research end and romance begin with Bill and Virginia? That line seems be getting more and more blurred.

"Masters Of Sex" returns on July 13th at 10 PM. Watch below.
