Asieh and her husband Volkan Arslan are guests for dinner. At the dinner table, Asia unannounced tells the host that Vulcan is having a relationship with her daughter and is cheating on her. He also adds that the man's daughter is pregnant by Vulcan. The daughter of the family is shocked and attacks Asia. Asia calmly gets up and goes out.

Before, Asiyeh, Vulkan and their son Ali are at home, and Asiyeh, who is a doctor, is preparing to go to the hospital. Vulkan has just returned from a business trip. Asia accidentally finds a lip balm in Vulcan's pocket.

Vulkan says that they gave it to him on the plane because of dry lips. Asia is satisfied. He then complains about his neck pain. Vulkan throws his scarf around Asia's neck while leaving the house. When Asia goes to the hospital, she notices a strand of golden hair on Vulkan's neck scarf and is shocked.

At that moment, a patient named Neel comes to Asia's room and complains about his insomnia and asks for a special medicine. Asia does not accept the prescription of that medicine and sends Neil out. He is obsessed with golden hair.

A little later, a woman named Gunul, who is one of Asia's old patients and whom Asia saved from death with her treatment, comes to Asia's room. She gives Asia an invitation card to her painting exhibition and asks her to come to the exhibition. Asia excuses being too busy and then looks at Gunol's golden hair.

In the afternoon, when Asiye goes to school to follow Ali, she sees Ali with her daughter Celine's classmate. Her classmate Sarap's mother is also there and after introducing herself, she tells Asia that she is Vulcan's assistant. Asia stares at Sarap's golden hair. At night, when Vulkan goes home, Asiye sarcastically complains that she didn't say that she made Sarap her assistant.

Vulkan says that Sarap has been his assistant for a year and he already told Asia and she must have forgotten. Asiya goes to Bahar's family friends' house, who are also their neighbors, and tells Bahar about the golden hair. Behar blames her and tells her that it is impossible for Vulcan to betray her and that they are in love.

When Asia goes home, she secretly checks Vulcan's phone. Just then an email arrives from a hotel thanking Vulcan for his stay last weekend. Asia is surprised and nervous. The next day, at Asia Hospital, she talks to Dr. Gulin, who is a close family friend of theirs, about the hair loss case and the hotel email.

Gulin denies such a thing and says that it is not possible for Vulkan to betray Asia and that the hair must have fallen on Vulkan's shawl from someone else and that the hotel was for a business mission. Asia is not satisfied and her mind is disturbed. Having realized from Sarap's words that Vulkan leaves the company earlier every day, he himself leaves the hospital to follow Vulkan. On the way to Neil, he sees the patient he visited the day before in front of a restaurant while a boy is beating him.

He plans to do something but keeps chasing Vulcan so he doesn't lose it. After the party, Vulkan goes to his mother's house to visit her. Asia also goes inside and is surprised to see Vulkan there.

Vulkan tells Asia that her mother is sick and lately she has been visiting her every day after work. Assiyeh tells Vulkan with shame that she doubted him and apologizes for thinking that Vulkan would betray her.

Vulcan looks surprised and hugs Ace. When Asiyeh goes to the kitchen while talking to Vulkan's mother's nurse, she realizes that Vulkan hasn't visited her mother in the last month. He is shocked to hear this and realizes that Vulcan is lying. Shab Vulkan is ready and wants to go out.

Asiyeh asks him where he is going and Vulkan says that Haluk's wife Goshlo, the owner of Ali School, has organized an exhibition and he wants to go there with this excuse to get to know Haluk in order to work with him. Asiyeh says that she was also invited to this exhibition and wants to accompany Vulkan. Vulcan fits but can't resist. They go to the exhibition together.

Gunol is happy to see Asia. He shows his drawings to Asia and Vulcan. A little later, Derin, the daughter of Gunol and Halok, comes forward and Gunol introduces her to Asia and Vulcan. After Darin leaves, Asia tells Gunol that tomorrow is Vulcan's 40th birthday and invites them to a party. Asia goes to the balcony.

He sees Neil again, who is working there as a waiter. Aasiya comes forward and asks about Neil's fight and beating. Neal sarcastically says that he doesn't care because she has a good life and didn't offer to help him the other day. Asiye says that her husband is cheating on her.

Neil is surprised and says she should get a divorce. Asiyah says that marriage is not that simple and she has a son. The next day, Asia goes to the restaurant where Neil works and asks him to chase Vulcan with a car that he provides. Neil agrees. A few hours later, Neil informs Asia that he was right and Vulkan went to a house and got into a car with a lady and left.

He sends the picture of the car to Asia. Asia gets nervous and worried. Neal advises him to search Vulcan's car, as he will surely find something. Asia bought a birthday cake for Vulkan and goes to the birthday party in the garden with Ali. Under the pretext of looking for a camera, he takes the switch of Vulcan's car and searches everywhere.

He finds a bag in the trunk with a phone in it. Asia turns on the phone and is shocked to see the photo of Vulkan and Derin, Gunol's daughter. He examines the other photos and realizes that Drin and Vulcan have gone out with Mert and Behar and Gunol and that everyone knows about it except him.

Then he reads the messages and finds out that Gunol informed Vulkan that Asia left the hospital early and may follow her. Asia becomes extremely nervous and agitated. But he controls himself. All the guests are gathered around Vulcan and Vulcan blows out the candles on his birthday cake and thanks everyone. Asia says to herself that you are all my enemies. I will not be a victim. You will see that I will give you an unforgettable forty years.

Hello, my name is Fatemeh and this is the footer of the 3rd part of Sadaqat Siz series.

Mert, who got drunk on Vulcan's birthday, plans to start giving a speech and tell everyone about Vulcan. Vulcan tries to stop Mert and ends up having to beat him to silence him. Asia takes Vulkan into the car and takes care of his hand, then greedily removes Vulkan's ring under the pretext of swelling his finger.

Vulcan asks Asia what they were talking about with Miss Gunol. Asia also says that they were talking about Darin. Vulkan asks with surprise who else is in the door?! Asia says: Don't you know Darin?! her daughter Vulcan pretends not to know Darin at all. Asia excuses a headache and returns home.

He angrily throws Vulcan's clothes into the suitcase and leaves the suitcases in the hall. At the birthday party, Drin goes to a corner and Vulcan walks up to him and kisses him.

Someone is secretly filming them. Darin argues with Vulkan and Asia because of their close and romantic relationship. Then he tells her that he can't bear it anymore and only gives Vulkan time until tomorrow to tell Asia everything and break up with her. Then he leaves greedily. Vulcan returns to the crowd.

Saran informs Vulkan that he has to work for a weekend to get the Rozha project. Ali, who had already promised to go to the soccer camp from Vulkan, gets upset upon hearing this news and asks Gunol to take him home. When Gunul takes Ali home, he notices that Asia is bored.

Asia tells Gunol that she knows about Vulkan's betrayal and complains to Gunol that he was hiding everything. Gonol sadly says that he is not to blame and that Vulcan promised to leave Dreen soon.

Asia says that she will throw Vulcan out of the house tonight. At night, when Vulcan goes home, he is very drunk. Asia inevitably takes him to the room to sleep, then thinks about Ali and decides not to tell Vulcan for now because of his excitement to go camping. The next day, Vulkan and Ali prepare to go to camp.

Vulkan doesn't go on a date because of Ali and asks the leaders to set up the meeting with a video call. At the hospital, one of the doctors named Artan, who is an old alcoholic man, is sitting in the board room and Asiyeh tells him that he will be fired because of the numerous complaints from the patients due to alcohol consumption. Artan gets angry and threatens Asia and leaves.

Darin goes to the hospital for a check-up and goes to Asia's room complaining of nausea and digestive problems. Aasiyah greedily asks questions about his sexual relationship, and Darin says that he is in a relationship with a married man who is going to divorce soon, because he does not love his wife and is forcibly living with him.

Asia gets nervous after hearing these words. He asks Darin for a urine sample and takes a pregnancy test with her urine and finds out that she is pregnant. She is shocked and angry and tells him about Darin's pregnancy. Then he sends Derin to Gonool for examination.
