Emanuelle, an unhappy housewife desperately seeks to free herself from the brutal sexual excesses forced upon her by her husband, Roberto. She attempts to find solace in an affair with a younger man, but is abused by him as well. In desperation she turns to her sister Giovanna, who runs a brothel, specializing in sado-masochistic games. With her help, she plots her revenge upon the men who have mistreated her with a display of sexual excess.

Following the success of the 1974 film Emmanuelle, many authorized sequels were created. The success also spawned many "knock-off" Emmanuelle films, which included the name Emmanuelle or its variants in their titles for exploitative reasons, but were not connected to the original series.
