The number of suspects in the murder of a property developer who had four unhappy marriages and had recently dismissed his brother-in-law is very high.

The murder of the mother and her two young children leads Behzat's team to the woman's husband, relatives who disapprove of the marriage, and a missing psychic.

The homicide squad investigates the murder of the cabin supervisor responsible for the dismissal of his colleague and the removal of a passenger from the aircraft.

When Ercüment calls Behzat to take responsibility for three new murders, the homicide team and a special team cooperate to organise an operation.

The team tries to hide the news about Eda and Selim from Harun on his special day. Behzat learns why Ercüment wants revenge and who killed Berna.
