From the back cover: "Certain to shock, certain to be talked about and certain to be a collector's item. This rare piece of music history was shot in 1979 but not released to the public until 1985. "A Certain Sacrifice" is the first project ever in which Madonna tested her acting abilities. Though raw and mostly improvised, it's clear that even as an unkown, 20 year old Madonna had intrigue which would be better displayed in her later projects."
Madonna plays Bruna, a sexy streetwise girl surviving in NYC lower East side. After she is raped, Bruna enlist the help from her followers/sex slaves to seek revenge upon her assailant.
The movie was a film students project that put a ad out in the papers looking for a leading woman. Madonna got the part.
