Our story opens one early morning, and we see Big Sister as she awakens in bed. We see the many ways she enjoys fondling her own body; as she arouses her own passions, she moves to another bed and awakens her boyfriend, and our Flick is off to a roaring inferno within three minutes of its opening scenes.

We then see Big Sister go to her own apartment, where she reveals that her business is prostitution. During her many clients appearing through the day, we are introduced to Little Sister, a somewhat naive little virgin. Big Sister teaches her the ropes and how to satisfy a man in almost every direction.

Later at a pot-party, Little Sister puts what she has learned into practical experience and decides Sex is quite the thing. Before the Flick is over, Little Sister has taken all of Big Sister's clients and Big Sister's business becomes Little Sister's Business. However, Big Sister decides she is tired of the business anyway, and returns to her real love (George), thus, revealing a socially redeeming factor . . and all is well.
