The third season of Showtime's Masters of Sex premieres July 12th, and this season will jump forward in time to the publication of Masters and Johnson's book in 1965, right as the sexual revolution was taking off. We also get a tease of the three way marriage Bill, Virginia and Libby were engaged in around that time here. The second season was fairly uneven last year, with some really good episodes paired with some material that was wildly hit and miss, but that may have been due to the show having to cover some of the gap years in the Masters and Johnson autobiography. This one should be back on track, as the duo are just about to become national celebrities with the publication of their research.
