Masters Of Sex season 3 premieres on 12 July on Showtime, and will focus on the aftermath of Dr William 'Bill' Masters (Michael Sheen) and Virginia 'Ginny' Johnson's (Lizzy Caplan) study being published.

The third season leaps forward from 1961 to 1966, as Masters and Johnson present their new book to a suspicious medical community.

Season three brings big changes to Masters Of Sex as the series is now set in 1966. As the season opens, the famed duo Masters (Michael Sheen) and Johnson (Lizzy Caplan) find themselves in the glare of the national spotlight as their controversial sex study is finally unveiled. Masters and Johnson's work will have a profound impact on contemporary relationships, especially their own evolving three-way "marriage" with Masters' wife Libby (Caitlin FitzGerald).

A new trailer released shows Virginia confidently saying, "We are the sexual revolution," in front of a group of what looks like journalists and academics who seem to be questioning their work.

The trailer also shows Libby Masters and Ginny sharing a hot kiss in bed. Libby will be playing a more prominent role in the series as part of the complicated three-way marriage with her husband and Ginny.

Margaret (Allison Janney) and Barton Scully (Beau Bridges) will also return in the series.

Showtime has announced that Tate Donovan will be guest starring in the upcoming third season of Masters Of Sex. He will play a confident scientist Graham, whose relationship with Margaret Scully brings them to Bill and Virginia's clinic, in two episodes this season.

The series is an adaptation of Thomas Maier's book Masters Of Sex: The Life And Times Of William Masters And Virginia Johnson, The Couple Who Taught America How To Love.

The third season is set to premiere on 12 July at 10 pm on Showtime.
