Masters of Sex is a period drama set in mid-twentieth-century St. Louis that dramatizes the working partnership between a hospital physician and his research collaborator as they organize one of the earliest laboratory studies of human physiology in their field.
What is Masters of Sex about?
Beginning in the 1950s at a Missouri university hospital, the series follows a respected obstetrician and the office administrator he hires as a research assistant. Together they design and run carefully controlled studies of the body's measurable physical responses, work that was unusual for its time and often carried out discreetly. Across its seasons the show tracks how this clinical project runs up against hospital politics, funding decisions, questions of professional reputation, and the shifting nature of the two leads' own working and personal relationship. Secondary storylines follow colleagues, hospital staff, volunteers, and family members whose lives are shaped by the research and by the social conventions of the era. The narrative moves gradually from the 1950s into the following decade, using the changing culture around it as a historical backdrop rather than a cause for comment.
Cast & crew
Michael Sheen plays the physician at the center of the study, and Lizzy Caplan plays the research partner who becomes central to the work. The ensemble includes Caitlin Fitzgerald, Annaleigh Ashford, Niecy Nash, Betty Gilpin, Isabelle Fuhrman and John Billingsley in recurring and supporting roles across the run. Michelle Ashford created and developed the series and is credited as its lead creative voice.
Context & significance
The series is an American production adapted from a nonfiction book about the real researchers whose careers it depicts, and it is presented as a historical drama. Its timeline spans roughly the 1950s into the 1960s, a period when formal scientific study of this subject was uncommon and socially constrained, and the show treats that setting as neutral historical context. It carries a 7.9 rating on IMDb, and episodes run about sixty minutes each. The genre is generally classed as drama with romantic elements.
