Noted psychologist Dr. George C. Chapman (Andrew Duggan), his assistant Paul Radford (Efrem Zimbalist Jr) and their staff are flying around the country conducting an anonymous sex survey of American women. They come to Los Angeles looking for volunteers in an affluent community called Briarwood. In a speech to the Briarwood Women's Club, Chapman says that “Too many women suffer from too little knowledge about a subject that occupies a major and crucial part of their lives...My associates and I believe that through our findings these women will come to realize that sex is decent, clean and dignified.“
