7x13 - Distretto di Polizia

Rosanna is raped in her own home by a masked man who seems to have left no traces: the young woman, shocked, only remembers that the attacker had a slight limp. Anna and Irene investigate the case which presents analogies with other unsolved rapes. Agent Guerra and Ingargiola are instead tasked with tracking down a prisoner who escaped, strange coincidence, on the same day that the theft of a precious piano is reported.
