5 donne per l'assassino

Giorgio Pisani, a journalist, has just returned from an international assignment only to discover that, in his absence, his wife has died during childbirth. However, a seemingly unavoidable tragedy takes an unexpectedly sinister turn when Lydia Franzi, his wife's doctor, reveals that Giorgio is sterile and therefore couldn't have fathered his wife's child. Soon after learning this terrible news, a mysterious, black-clad killer begins stalking the city, viciously murdering pregnant women who were in the same maternity clinic as Giorgio's deceased wife. Could Giorgio, in a fit of guilt-ridden madness, be responsible for these horrendous crimes, or is he an unwitting participant in the sinister plan of an even more wicked culprit? (Vinegar Syndrome)
