A group of women gather at a fertility clinic, where Dr. Margherita Dumas offers a revolutionary treatment for their infertility problems. A year later, each of them gives birth to a healthy baby boy.

Thirty years later, a killer begins to wipe out the children born as a result of Dumas' programme. Detective Inspector Harry Houston is assigned to piece together the case and bring the killer to justice.

But with little time and even less clues, can Harry and his team find the link between the past and the deaths of the progeny of Clinique Sobel?
