Fifteen year old Sylvia is found hanged, an apparent suicide.

But after Inspector Silvestri (Cassinelli) and the assistant D.A. (Ralli) launch an investigation, they uncover an underground ring of schoolgirl prostitution, kinky sex...and a killer out to silence the whole mess.

This action-tinged mystery is less a giallo than Solange, and more of a police thriller. But it's entertaining nonetheless.

Notable highlights include a nailbiting cat and mouse chase with Ralli and the killer.

Look for Granger as Sylvia's grief-stricken father. Nice Stelvio Cipriani score.

Also known as The Coed Murders as well as The Police Want Help.
