Rock Hard

Adonna, lead singer for the Sexelettes, an all-girl, heavy metal band, has a lot going for her in the steamy backstage saga of the music industry. Many are helping Adonna get her hard rocks off along the way are:

Fornicating Phil (Jerry Butler), the groups manager; Sinfully Seductive Cindi Looper (Nina Hartley), one of Adonna's backup singers who deos much more with her luscious mouth than just sing; Ultra Box (Patti Cakes), another slutty Sextelette whose name says it all; Billy D.J. (Billy Dee), who's prepared to do a lot for girls, provided that they do a lot for him first; Joan Dominatrix (Lily Marlene), a booking agent that no club owner dares to refuse.

...plus enough miscellaneous promoters, studio execs and program directors to give Adonna's leading stud all the stiff competition necessary to make a story so sex-saturated that it could only have been based on the Hollywood music scene.
