“Sangue del tuo Sangue” narrates true stories through reconstructions and interviews. The episodes are based on stories of family crimes. In every episode, the family’s story is narrated without revealing the name of the killer or victim. Only at half of the episode, viewers will understand who was killed by “Flash of your flash”. The last part is dedicated to the scientific investigation, recreated in every single detail in order to understand who is the killer and why he decided to commit a murder. Simona Ruffini, criminologist and writer, comments and analyzes the highlights of every story.
