Petra Delicato is a Police Inspector who abandoned the lawyer career to join the Police squad in Genoa. When a serial rapist begins to strike in the city, she is appointed to solve the case, supported by Assistant Inspector Monte.

A brutal murder throws Petra and Antonio into the cruel underworld of dog-fighting. A veterinarian, an ethologist, and a bastard named Creepy will be their road companions in an investigation punctuated with murders along the way.

A series of brutal amputations, in a macabre ritual, leads the investigators to a sect with roots in Russia. Aided by the Russian police and in particular by the charismatic Egor, Petra and Antonio solve a nightmarish puzzle.
