Co-written by Massimo Dallamano, this is the third film in the thematic 'schoolgirls in peril' trilogy. The first two films – What Have You Done to Solange and What Have They Done to Your Daughters – were directed by Dallamano himself and are among the upper bracket of the giallo sub-genre as a whole. Trauma, on the other hand, was only co-written by Dallamano, its director was the much less known Alberto Negrin. It would only be fair to say that it's clearly the least essential entry of the three. However, as is the way with most gialli, it's still pretty involving and entertaining.
The story follows a detective who is investigating the rape and murder of a young girl. On the back of this other murders start. This is one of those gialli that is quite heavy on the police procedural side of things, with less emphasis on the various shady characters on the periphery of the story. It more or less gets away with this as Fabio Testi - who plays the cop - is a good presence. The movie overall lacks the sense of style and tight plotting of the first two films but it ramps up the sleaze factor with extended shower scenes and a sex-party that incorporates the use of a somewhat prominent dildo. Of course, the very fact that the young ladies in this are members of a girl school merely adds to the overall shadiness! The murder-mystery is certainly good enough, although admittedly by-the-numbers for this sort of movie. Perhaps surprisingly, the violence has been played down somewhat. Murder scenes are often very important in gialli but in this instance they aren't memorable at all and certainly not graphic in any way. It's more focused on the mystery and this is eventually wrapped up in a slightly unpredictable way it has to be said and for that it does receive plus points. Additionally, Riz Ortolani's soundtrack is once again very good and adds a lot to accentuate the suspense.
