Eve, a victim of childhood sexual abuse, and her lover Frank, a disc jockey, live in the San Francisco Bay Area.

Frank is dismayed that Eve has gone to a boxing match featuring African American pugilist Johnnie Keyes.

At the ensuing orgy, Frank happily enjoys the charms of a friend's wife, but Eve is horrified by the hedonism and they fight afterwards.

At an orgy featuring all manners of sex, gay, straight and interracial, Eve couples with an African American gentleman while the jealous Frank watches.

The Supreme Court's 1973 Miller v. California decision, which was decided on 21 June 1973, adversely affected the mainstream release of porn films, including Behind the Green Door.
