Ilgaz put forward the first theory in the well-murders, which remain a mystery, by saying that "the killer creates a family for himself". Ceylin does not hesitate to research her own thesis by side ways. With the mysterious death of his sister Neva and the murderer not being found, Pars is going downhill psychologically with each passing hour. The end of this slope will lead him to make a choice between his profession and his feelings, what will Pars' choice be? When the identities of all those who were removed from the well became clear, the investigations carried out became even clearer. However, the new suspicions that arise force Ilgaz and Eren to remain vigilant. Eventually they will have to be dragged into a choice they don't want. Ilgaz and Ceylin are working hard in their own way to untie the difficult event knot; However, at the end of the day, with the development that will shake everyone, they have to understand that nothing will be the same as before.
