In Palermo, a German prosecutor is found murdered - of all places, on the street corner of transvestites. Serena Vitale wants nothing to do with the case, as African smuggling gangs are taking up all her time, with many looking to profit from the plight of refugees. However, the prosecutor was investigating the mafia in Germany, and Serena Vitale is well aware that this is certainly not a crime of passion. She has no choice but to throw herself into the investigation.
