Hoping to develop a drug to awaken his long-comatose sister, genetics engineer Murat attends a shamanic ritual to research the effects of ayahuasca.

The events that happened during Murat's lost hours are revealed. The police question those who were the last to see Ayhan before his body was found.

Selin receives a message alluding to a secret she's keeping. Murat tracks down the doctor who was supposed to perform Ayhan's heart transplant.

During a forced hospital stay, Murat tells his uncle about being taken to the secret operating room, where he learned why his father was murdered.

After Ceyla decides to try Murat's experimental drug on herself, her personality changes dramatically and she visits Murat at his home.

Selin obtains security camera footage that shows who's been leaving the messages for her. Murat gets a call inviting him to meet his father's killer.

At a nightclub, Murat's alter ego witnesses an altercation between one of his students and her boyfriend, and takes matters into his own hands.

Salim and Ferit help Murat cover all tracks linking him to the body in his car. Doğan confesses to Utku's mother the part he played in Utku's death.

Murat awakens to find a body and cleaning crew in his home, but the cleanup goes awry. Ezo begins repeating a foreign-language phrase in her sleep.

Yıldız orders Vecdi and Süha to kill Doğan, who now knows too much. Suspicious of Murat's recent odd behavior, Selin tracks down fired doctor Ömer.

In her sleep, Ezo asks to speak to Ceyla, to whom she makes a desperate plea. Murat learns how Yıldız is connected to his father's death.

Ezo gets revenge. Ceyla makes alarming allegations against Murat that lead Selin to accept a dinner date with him in hopes of getting a confession.
