Liam Neeson stars as Kinsey, who in 1948 irrevocably changed American culture and created a media sensation with his book Sexual Behavior in the Human Male. Asking thousands of people about the most intimate aspects of their lives, Kinsey lifted the weight of doubt and shame from a society in which sex was hidden, and knowledge was dangerous. His work sparked one of the most intense cultural debates of the past century – a debate that rages on today.
