As an attempted murder takes place in a company, Det. Asmaa uncovers the circumstances of the incident. Rawan suggests that her husband, Saud, visit a psychiatrist because of the many disturbing dreams he has. Saud resents the interference of his sister Hind with his life.
As Asmaa is taken aback by the patient Mahmoud being thrown from the hospital balcony, she investigates the matter, while his brother Fahd comes under suspicion and Mahmoud falls in a coma. Saud is placed on the waiting list for a heart transplant and agrees to visit a psychiatrist.
Hind files a report against Rawan for giving Saud medicine that harms his health, and she asks the psychiatrist for documents certifying Saud's mental incompetence in order to file a suit against him placing him under legal guardianship. Saud sees in his imagination the image of him killing Mahmoud.
Saud informs Det. Asmaa that he saw Mahmoud's murder happening in front of him, leading her to the instrument of the crime. He suffers a heart attack and is taken to the hospital, where he falls into a coma. Nasser finds a video of his two brothers, Mahmoud and Fahd, fighting with each other.
The hospital administration suspends Nader from work and questions him in the case of Saud, and the latter discovers that Rawan has changed Saud's medication. Asmaa is shocked to find the instrument of the crime and a lot of money in her mother-in-law's house.
Saud sees his wife, Rawan, trying to remove his oxygen mask and kill him. Meanwhile, the forensic pathologist receives an anonymous threat asking her to hide the instrument of the crime which Asmaa found.
Asmaa informs her colleague, Det. Dhari, of her suspicion of her husband, whereupon she arrests him. Dr. Fajr tells Asmaa of the threatening message, while Nader gives Hind an audio recording of Rawan confessing that she switched Saud's medicine. Mahmoud wakes up from his coma.
Saud discovers Rawan's low chance of getting pregnant, and that she lied to him about her pregnancy; he confronts her with the audio recording where she confesses to switching the medicine. As the police question Mahmoud and confirm that Asmaa's husband tried to kill him, he's brought to trial.
