Episodes
Season 1
Pilot
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.
Race to Space
On the heels of Masters’ proposal that they participate in the sexual response study, Johnson considers the best course of action to keep her job – only to find she no longer has one. The study has been forced out of the hospital and Masters believes Johnson is to blame. As Johnson fights to save her job and struggles to care for her kids, Masters moves his study to a brothel. But Masters soon discovers that the chaos of the cathouse is unmanageable without Johnson’s help.
Standard Deviation
Masters and Johnson continue their research in the brothel but skewed data confirms that Masters must get the study back into the hospital. At the hospital, Johnson is surprised to learn that a distinguished new doctor on the OB/GYN floor is a woman who has no interest in female solidarity. Meanwhile, Libby struggles to conceive and Dr. Ethan Haas gets the case of a lifetime – a woman pregnant with quadruplets.
Thank You for Coming
With the study back in the hospital, Masters and Johnson recruit new participants on campus. But Johnson is shocked when her ex-husband George, who’s crashing on her couch, wants to sign up. Masters’ mother comes to visit, but her new take on life stirs up painful memories of his childhood. And Libby’s attempt at playing matchmaker with Virginia and Ethan doesn’t go as smoothly as she’d hoped.
Catherine
When Masters and Johnson expand the study to include couples, they discover that the science of sex is easily complicated by the mystery of attraction. Johnson tries to connect with her son who prefers his dad. In anticipation of his baby’s impending arrival, Masters experiences anxiety about becoming a father. And Dr. Ethan Haas learns that dating the provost’s daughter could impact his medical career.

And Langham finds an unlikely cure for his sexual dysfunction in Margaret Scully.
All Together Now
