Angela Russo, a sixteen-year-old girl, is found dead in a river, having been fatally violated with a large blunt instrument. Inspector Di Salvo is assigned to the case and focuses his investigations on St. Theresa's, the exclusive school where Angela boarded.

Bizarre "accidents" start to befall the girls: Franca is injured when someone causes her horse to bolt and Virginia nearly breaks her neck on marbles left at the top of a staircase.
