"Masters of Sex" is the new hot series that premiered September 29, 2013 on Showtime in the U.S. It is all set to make its debut in Australia on channel SBS, this Thursday.

Developed by Michelle Ashford, the principal characters of the new series are Dr. William Masters (Michael Sheen), an obstetrician, and Virginia Johnson (Lizzy Caplan), a night-singer turned researcher. The two research and explore human sexuality at Washington University. The series is set in the 1950s.

According to Showtime's pilot episode synopsis: "Dr. William Masters, Washington University's foremost OB/GYN, runs a successful medical practice by day and conducts a secret study of human sexuality by night. Former nightclub singer Virginia Johnson joins the hospital secretarial staff and proves herself to be an asset to Masters' work."

"Masters of Sex" is based on Thomas Maier's biography "Masters of Sex: The Life and Times of William Masters and Virginia Johnson."

The book offers a look at William Masters and Virginia Johnson's "pioneering studies of intimacy, and the sexual revolution they inspired. Masters and Johnson began their secret studies in a small Midwest laboratory, and soon became the nation's top experts on sex," according to the introduction of the book.

Why should you watch "Masters of Sex":

"If you watch 'Masters of Sex,' you will score chicks," Lizzy Caplan told GQ as quoted by Huffington Post. "This is everything your readers need to know ... I know that the show will be equally relevant to men and women, if for no other reason: tits!"

Talking about the scenario in 1950s, Caplan said that "millions of women took all of the blame for all the problems in the bedroom. They basically figured out that the female body is far better equipped for sex than the male body. Women can have multiple orgasms; men cannot. They're actually the sexual athletes, not the men."
