Laura's obsession is to bury the past: a murky past made up of bad marriages that have indelibly marked the relationship with her daughter Floriana. When after years Laura decides to reopen herself to love, the past forcefully comes back to the fore to swallow mother and daughter once again in their tragic destiny.
In love, Margherita is obsessed with perfection: anyone who is not perfect is not only not worthy of being with her, but deserves to be eliminated. When she finally seems to have found the perfect man, however, dissatisfaction forcefully comes back to the surface and the chain of murders continues its course.
Chiara is convinced that her husband is cheating on her, but the certainty exists only in her mind. For this reason the woman cannot help but control him constantly, thus entering into endless paranoia. The object of her frustration is her new neighbor Manuela, whose life she makes unbearable with constant stalking, causing her to fall into fear and desperation. Manuela tries to talk to the people close to Chiara — her mother-in-law, her husband himself — and the police, but no one is able to grasp the warning signs of a tragedy that will result in a brutal murder.
