Fascinated by her roommate Kristi's illicit sex life, the young professional Brenda covets Kristi's unending parade of dominant men. She is tempted into a web of ecstasy when she agrees to perform for the "Master" Kristi has been seeing. Without ever allowing his plaything to see him, the Master first guides her into bed with Kristi-and then into submission to her as well as to the Master himself. After the Master tempts Brenda into a meeting where she is savagely disciplined and sexually used, Brenda surrenders all control-entering into a pact of mutual submission with Kristi that leaves both girls utterly at the mercy of their Master. But what dark plans does this unseen man have for his two willing slaves?
