Dhay dies during the bombing of businessman Al Sayoufi's car. At the morgue, Officer Iyad is surprised to discover that Dhay has three different lives. Her father confirms that she lives with him, her husband, Montaser, says they live abroad, and her fiancé, Adel, recognizes her.
In a flashback, Dhay's father refuses to let her continue her master's studies, and a teaching assistant at the college plots to make her revolt against the other students. Dhay loses consciousness and is saved by Fawzia and her granddaughter Rahma. Dhay claims that her name is Doha.
Hassan, Dhay's father, meets Adel and Montaser and tries to find out their relationship with Dhay. He remembers when Dhay was forced to undergo a virginity test because she refused to marry her cousin Bilal, and when her mother fell from the balcony and was taken to the hospital.
Montaser receives threats from the mafia for failing to locate the research conducted by Dhay. It turns out that Dhay is not dead, and she asks her friend Samah to help her prove the validity of her research and reveal the real perpetrator of the assassination attempt.
The officer accuses Hassan of pushing Dhay's mother off the balcony, and Dhay tells Samah about Montaser's betrayal of her and their divorce before she returned to Egypt, and the murder of her university professor because he agreed with her to complete her research.
Iyad interrogates Issam, Dhay's colleague, who tells him that he proposed to Dhay, but her father refused after he seized her inheritance.
After Fawzia discovers the truth about Dhay, Dhay tells her what happened to her and her escape from a gang trying to seize her research. Dhay suspects that Adel stole the research flash drive, and Montaser returns and leaves Dhay's daughter with Hassan.
Dhay visits her mother after she leaves the hospital and is surprised to find Iyad trying to gather any information about the circumstances of the accident. The police find the flash drive next to the wreckage of the bombed car.
Montaser tries to convince Adel to cooperate with him to find the flash drive, and Dhay reveals to Issam that she is still alive and asks him to help her complete her research.
Adel is surprised to find that Dhay is still alive and blames him for selling her land to Hassan under the general power of attorney. Issam agrees to help Dhay and tells Samah about it.
Dhay takes her daughter with her and sends a message to her ex-husband, Montaser, claiming that their daughter has been kidnapped. Dhay discovers that Montaser's lover, Hajar, is not dead, and Samah hides from Dhay Issam's approval to help her.
Iyad thinks about withdrawing from the case, then asks the prosecution for permission to exhume Dhay's body, and Dhay asks Samah to open a bank account in her name.
Dhay seeks to perform surgery on her daughter and agrees with Issam to take her to the college lab where he works to conduct her research.
Adel publishes an advertisement for the sale of the house, and Hajar claims that she wants to buy it, while Saad tries to blackmail Samah into working with him selling medicine on the black market in exchange for not exposing her relationship with Dhay.
Iyad discovers that the research on the flash drive is related to Dhay and discovers Al Sayoufi's connection to the matter. Hajar continues to get closer to Adel, hoping to reach the flash drive, with Montaser's instigation.
Dhay worries about Iyad searching for her, and Montaser begins to obtain official papers proving his right to Dhay’s inheritance.
Iyad confirms that Dhay is still alive, that there is a danger threatening her life, and he suspects that there is a connection between her and Al Sayoufi's death.
Iyad meets with Dr. Souad to gather information about Dhay. Issam and Samah agree to complete Dhay's research without her knowledge. Bilal is surprised by Dhay's visit, asking him to hide her in the village for a while.
Hajar tells Adel that she is Montaser's wife, and Dhay decides to return to Cairo to perform surgery on her daughter. Iyad and his colleague Shawqi continue their investigations into Dhay's research.
By tracking Dhay's daughter's tablet, Iyad finds out where she is in the hospital, and the police arrest her.
Dhay tells Iyad everything about her research, and Samah threatens Saad with expelling him from the pharmacy for selling drugs on the black market.
Omar supports Dhay in her case and testifies in her favor, and investigations continue with Dhay to reveal her relationship with Al Sayoufi.
Dhay tells Iyad that she is staying with Fawzia for a while until she can prove her innocence, and Dhay reveals that she hired a sniper to kill Al Sayoufi.
Dhay confesses to trying to kill Al Sayoufi, asks her father to deliver medicine to her daughter, and then devises a plan to escape from prison.
Dhay escapes from prison, and Iyad succeeds in reaching her. Adel tries to take Dhay's daughter and leave her with Fawzia, but Montaser tries to intercept him.
It becomes clear that Iyad helped Dhay escape and tried to convince her to bring down the international gang.
Iyad and Dhay set up an ambush for the foreign pharmaceutical company's employees, and Montaser threatens Hajar and forces her to return to work with him.
A member of the company negotiates with Dhay to hand over the drug formula, and Montaser can reach his daughter to force Dhay to hand over the drug formula to him.
Younis and Shawqi confront Iyad about helping him smuggle Dhay. After Dhay contacts the company representative, Iyad finds him dead, and Dhay asks Montaser to give up custody of his daughter in her favor.
