The first season of Masters of Sex began airing in the United States on September 29, 2013. The series is the television adaptation of Thomas Maier's biography Masters of Sex: The Life and Times of William Masters and Virginia Johnson, the Couple Who Taught America How to Love. It stars Michael Sheen as Dr. William Masters and Lizzy Caplan as Virginia Johnson.

The first season takes place in 1956 and 1957.

Plot Edit

In 1956, a nationally renowned fertility specialist, William Masters, met a former nightclub singer, Virginia Johnson. Bill proposes a controversial new study on human sexuality but is rejected by the university. He begins the study anyway with his new secretary. The study goes to a brothel, where he meets Betty DiMello, and goes back to the study after blackmailing provost Barton Scully with his homosexuality.

Bill's wife, Libby Masters, wants a child, but Bill cannot tell her that his sperm count will make it impossible to conceive a child. She eventually becomes pregnant through fertility treatments, but suffers from a miscarriage. Despite Bill not wanting to try again, Libby becomes pregnant again and gives birth at the end of the season.

Bill and Virginia begin having sex themselves for research in the study. However, after Bill pays her for her work (as they do to all their subjects), Virginia feels demeaned, and later quits. Bill is unable to cope with Virginia's departure. The presentation of the study at the University turns out to be a disaster, and Bill is fired from Washington University. The season ends with Bill on Virginia's door step saying he can't live without her.
