The departure of Lolita and Danilo for a dream holiday in Egypt is postponed due to the news of a tragic accident that happened at sea: two young boyfriends died during a diving excursion. Already from the first investigations Lolita realizes that something does not return in the dynamics of misfortune but still does not know that, to reach the truth about what happened, she will have to put her own life at risk.

This time Lolita finds herself having to investigate an unusual and tragic death at the same time: the teacher of an exclusive high school in Bari was killed at the wedding banquet of one of her colleagues. But when the case seems solved, it is the disappearance of a boy from that high school to open a new, chilling investigative hypothesis to the vicequestore.
