In an early 20th-century American society marked by sexual repression and taboo, an enthusiastic and curious biologist, Alfred Kinsey, decides to delve into the complex world of human sexuality. Driven by the need to understand sexual behavior, Kinsey embarks on a series of groundbreaking investigations that will challenge the conservative values of his time. As he immerses himself in interviews with countless individuals, his study becomes a monumental work that not only collects data on sexuality but also exposes the hypocrisy and ignorance of American culture.
Kinsey's personal life is no less intriguing; his marriage to Clara, a pragmatic and understanding woman, becomes another central aspect of his research as he navigates his own doubts and discoveries in the personal realm. With the support of his team, Kinsey covers everything from heterosexuality to homosexuality, provoking both admiration and disdain in a society unprepared to accept the diversity of human sexuality.
As his work gains notoriety, Kinsey faces increasing criticism and social pressure, continually challenging established norms and those who feel threatened by his findings. The film becomes a captivating and humanizing journey about sexuality, the pursuit of knowledge, and the impact that these discoveries have on people's lives, pushing the boundaries of his time.
