The two brothers, Karim and Hassan are working together in their father's trade. Before his death, their father asks Karim to look after his brother Hassan. As they grow up, Karim gets married, and have three daughters, whom Hassan loves dearly, but Karim's wife, Jazia, can't stand Hassan.
Hassan quarrels with the lawyer and asks him for his money or the restaurant. He goes to the company to meet Karim, who also quarrels with him. After Karim kicks him out, he falls unconscious and the ambulance takes him to the hospital.
Karim's wife goes with her daughters to the hospital and her husband is in a critical condition, while Hassan gets into a car accident and is also hospitalized. Karim dies after his condition deteriorates. Karim's wife is devastated and her mental state is very bad.
As Hassan goes to Jazia to console her, she tells him that the Public Prosecution wants to open Karim's grave because she suspects that he was killed. Hassan takes his brother's place in the company and asks the secretary not to let Karim's friend, the lawyer, enter the company.
As Hassan takes control of the company and starts gambling, Karim's daughters dislike him. The lawyer reads Karim's will which states to give Hassan third of the inheritance and the rest to Jazia and the girls, much to Hassan's discontent. Hassan tries to find any loophole with the lawyer to get more.
Hassan gets upset when the secretary tells him that the police has located his car. Hassan hires guards to protect him and the house and tells his friend that Rahim and the lawyer might find out about him.
The lawyer tells Jazia that Karim has a son from another wife and accordingly he will inherit with them, which makes her sad and feels betrayed; she tells Hassan the news. Hassan fires Karim's close friend in the company and threatens him.
Hassan doesn't find any evidence of Karim's second marriage. Jazia tells her friend about Karim's betrayal. As Karim's daughter, Yasmine, is setting up a tourism company project, her father's friend advises her not to sign any document that Hassan gives her without referring to him.
Hassan's men take the young man who was being held with them and throw him in the street. As Hassan makes sure that there is no suspicion around him, he plots with Yasmine's friend, Marwan, against her and gives him money so that he can watch her and tell him everything in her company.
Hassan offers Yasmine a partnership, and she agrees. Jazia finds Hassan being kind and helping her daughter Yasmine while she hates her fiancé. The lawyer discovers a secret in a document sent to him, after which he contacts Hassan.
The lawyer tells Jazia that the investment he made with Yasmine makes her lose a large percentage in the company and asks all the heirs to meet in the office to divide all the inheritance, especially with the appearance of the fourth daughter.
The lawyer tells Jazia, her daughters and Hassan that Karim registered the largest share of his fortune to his daughter Sarah from his second wife, who is in Oran. The girls search for Sarah online out of curiosity. The young man who had the accident dies in the hospital.
Adl comes from court to inform Sarah to come to the lawyer's office to receive her share of her father's inheritance. As Hassan wants to reach Sarah, he finds a solution to prevent her from inheriting, and the young man whom he hired to watch Yasmine asks to marry her sister.
Jazia goes to the house of Françoise, Karim's second wife, to see her. Hassan also goes to her and threatens her, as he tries to prove that Sarah is not Karim's daughter by forging the DNA. Sarah asks Marwan to tell her about her sisters and wants to get to know them, but her mother refuses.
As Marwan meets Sarah at Hassan's restaurant, Hassan learns by chance from Rahim that she is his niece Sarah. The maid steals a file from Hassan's safe and runs away. Sarah meets her sister Yasmine by accident in the company.
Sarah goes with Marwan to Hassan's office, quarrels with him and threatens him if he approaches her mother again. Yasmine refuses to accept or deal with her sister, as the lawyer tells her that Hassan is trying to deceive her.
As Hassan files a case challenging Sarah's lineage and demands that the DNA be taken, she refuses, which makes him feel victorious. Sarah goes with Marwan to his house to introduce her to his mother. Hassan advises Karim's wayward daughter, Manal, to take care of herself.
While Yasmine and her colleague are looking into the company's files, the police go to Hassan's house to summon him for investigation. During the investigation, Yasmine's lawyer, who doesn't get along with Hassan, attends.
As Hassan asks Jazia to attend the meeting of the board of directors, she agrees to request an advance from the bank. He also asks her to make Yasmine stop consulting her father's lawyer. The police arrest Abdo after seizing drugs in his car, while he accuses Hassan, who denies his connection with Abdo.
During the meeting and after the approval of the majority, Jazia also agrees. Jazia goes to reconcile with the maid after accusing her of theft and firing her. Jazia also discovers that her young daughter, Manal, is taking drugs. Hassan asks his men to keep an eye on Sarah.
Amina fires Marwan from the company and asks him to stop watching Sarah, but he goes to Sarah and her mother and warns them of her. Françoise suspects that Hassan had a hand in Karim's death. Manal is caught cheating while taking her exam.
Hassan asks Yasmine to drop the case she filed against him regarding fraud in exchange for not making her fiancé go to prison; she goes to the lawyer to withdraw the case. Manal lies to her mother and tells her that she is about to pass the exams while she goes to the nightclub.
Amina tells Yasmine that the DNA result is negative and that Sarah is not their sister. After Jazia discovers that Manal was expelled from college for cheating and quarrels with her, Manal runs away from home. Hassan goes to the medical lab and asks the doctor to confirm the result.
Yasmine gets married and the wedding takes place at home, but Manal does not attend, which upsets her mother. The police arrest Manal after they searched her car and found drugs in her bag.
As Jazia learns that Manal is in prison and accuses Khalid of being the reason, Marwan goes to Manal's friend and beats him. Amina gives the analysis result to the lawyer, which proves that Sarah is not their sister. Sarah becomes suspicious when she hears her mother talking to someone on the phone.
After Karim's lawyer's secretary makes a copy of the DNA test, she tells Hassan that the result is negative. Hassan gets angry and tells Amina that she should have consulted him in filing a case regarding Sarah's removal from the inheritance.
Sarah quarrels with Marwan for helping Amina get a sample for the DNA test. Yasmine and Amina decide to file a case to prove Sarah's parentage. Karim's friend tells Hassan that he suspects the lawyer of having a hand in Karim's murder. Hassan stops any action against Sarah and asks to meet her.
Hassan tells Sarah that she is his daughter, as he found out that her mother had an affair with Hassan and got pregnant with him, but he abandoned her, so Karim married her on paper. Karim's lawyer is the one who killed him by poison, as he orchestrated Sarah's story to split the inheritance with her.
