The fate of the rootless is changed when they find a baby in the garbage one night. Mercan becomes a mother to the rootless at a young age. Ali is the father… Rootless people who can't take care of themselves try to raise this baby, even if it's with what they find out of the garbage. But it won't be easy. Because the same night is pregnant with a great sin. This secret, which the rootless people will carry on their backs for life, will hurt Ali the most. Both Çatal who begged them and the secret of that night will not leave them. The 23-year-old mystery curtain for these street children who survived by clinging to each other will be reopened when Gülayşe falls in love and Barbaros Commissioner enters their lives...

Barbaros Commissioner finally kept his promise to Nizam Eyüboğlu and found his daughter Lara. However, baby Lara is not abandoned. She is now Gülayşe of the Firebirds. How will Barbaros manage to separate Gülayşe from her siblings? Firebirds, on the other hand, will face the danger of losing their nests due to lack of identity and money. Can they find a way to avoid ending up on the streets again? In the past, Köksüz Tayfa, who escaped from Çatal and had no roof over their heads, ended up on the streets with a forty-day-old baby. What will the Köksüz family, who became the family of the baby they found in the garbage, struggle to keep their little baby alive?

Ateş Kuşları, whose nests are destroyed, are left homeless and return to the streets where they started. Will Ali be able to save his family from the streets this time? In the past, Köksüzler people try to be a family and survive in their first home they built on the top of Istanbul. Zıpkın cannot bear what Gülayşe has suffered and finds a way to bring Mercan to Eyüboğlu mansion as a servant so that the secrets of the past will be revealed. Will this path help them achieve their goals? On the other hand, Gülayşe is surprised to return to the street, her first home after being found in the garbage, and thinks that she has left Barbaros forever. However, Barbaros went after them to take Gülayşe to her father. Although Gülayşe is unaware, Barbaros is watching her at all times.

While Ali is trying to protect Gülayşe from Çatal and Mercan and Zıpkın are trying to reunite her with her father, Gülayşe is disillusioned with Yakup and dives into dangerous waters. She enters the fork's lair. She also steals Catal's stash. Mercan and Zıpkın follow the traces of the past in Eyüboğlu Mansion and are determined to prove the culprit. Harpoon's plan begins to work smoothly. But will Eyüboğlu hire Mercan without an ID? Will Zıpkın and Mercan find the woman who trashed Gülayşe that night twenty years ago? Çatal, who is after Gülayşe, is now after her money and is even more dangerous. That money will get Catal one step closer to the Firebirds. The fraternal bond of the Firebirds will give a completely different test this time. In the past, the rootless people who tried to look at Gülayşe as their eyes by running away from Çatal finally got caught. How will the Ateş Kuşları manage to protect Gülayşe this time?

Çatal is after Köksüzler again. Gülayşe is determined to help all children with the money she stole from Çatal. Seeing Gülayşe's stubbornness, Ali finds a solution that destroys Gülayşe's dreams. But it's too late now. Zipkın is ready to break the Köksüzs oath in the mansion he entered with Mercan, secretly from Ali. As long as Gülayşe is reunited with her father! Or will Zipkın burn Ali and tell Nizam all the truth? Barbaros does not allow the homeless Gülayşe to stay on the streets in this cold. He wants to help Gülayşe, but Ali stands against Barbaros. This time, Gülayşe is Ali's target for his love. In the past, Zıpkın and Kara do their best to keep Gülayşe alive. It will not be easy to protect Gülayşe without Mercan and Ali on the streets.

Gülayşe's anger towards Ali darkens her eyes. She asks Barbaros to kidnap her. While Gülayşe and Barbaros, who are riding the dragon, bid farewell to the rest stop, the Fire Birds face losing Gülayşe, whom they cherish. To find Gülayşe, Ali and Zıpkın are after Mete, the person who knows Barbaros. Naz and Menderes are in front of Gülayşe, the baby they left in the trash 20 years ago. The Firebirds' worst nightmare comes true. This time, Gülayşe falls into Çatal's trap. In the past, Ali's plan works and they manage to escape from Çatal's hands. But this time Kara is not there. The same car follows Kara, who is separated from the Firebirds.

Gülayşe wants to live the love story she has dreamed of with Barbaros, even for one day. She will go out to dinner with a man for the first time. He starts preparations with excitement. But the facts that await Gülayşe will turn this fairy tale into a nightmare from which she will want to wake up. The day Nizam has been waiting for finally comes. He is in front of the television. In tears, he calls out to his daughter, who has been missing for years. There is no escape now. Mercan cannot delay Zıpkın any longer. He is at the door to tell Nizam everything. In the past, Mercan creates future dreams for the Köksüzs about the time they grew up. She talks about the man who will appear before Gülayşe as if he has seen these days, unaware of the pain they will experience.

Zümrüt shatters Gülayşe's dreams with Barbaros. Gülayşe is now sitting across from Zümrüt at dinner. So, will Gülayşe accept Zümrüt's marriage proposal for the sake of her family? Şirin's big secret, which she buried years ago, comes to light. Barbaros is the son of Çatal. Barbaros' real test begins now. Will Barbaros learn that his greatest enemy, whom he has been chasing for years, is his father? How will Şirin, who has been hiding this truth for all these years, look at Barbaros' face? In the past, the Köksüzs will follow Sabit's inventive ideas for their only baby, Gülayşe.

Although Gülayşe tries to set herself on fire to protect her family from Çatal, neither Ali nor Barbaros will allow it. This time, Gülayşe stands up against Zümrüt herself to prevent Ali from becoming a murderer. The sharp knife in his hand will either return to Zümrüt or to himself. Gülayşe is finally in front of Barbaros, whom she fell in love with at her first meal. While Barbaros tries to get rid of Çatal's game, Sabit learns Barbaros' big secret. Barbaros is a police officer. So, will Gülayşe learn this secret of Barbaros? While she thinks she has met her love, will this lie be revealed? In the past, a great test awaits the Kökless people. Sabit meets his mother on the streets. Or will a new life begin for the Rootless?

Çatal interrupts Gülayşe and Barbaros' happy moment alone. But Çatal does not kill Gülayşe. He gives Barbaros such information about Gülayşe's past that Barbaros' route changes. Gülayşe, unaware of the circle of secrets around her, dreams of helping orphans with Barbaros. She prepares an iftar table for them. Nizam is now live on the TV they watched while eating together. He calls out to his daughter. All of Gülayşe's attention is on the tearful father on television. Ali is devastated when he learns that Mercan works in the mansion. This time, he was hit by the closest person in his life. He takes his anger with him and abandons the Firebirds. He takes his breath next to Fidan, who emerged from the pages of the past. Mercan will go after Ali as soon as she hears the name Fidan. In the past, Köksüzler, who could not leave Sabit alone with his family, meets Fidan.

Is it the end of the road for the Firebirds? After Nizam Eyüboğlu's live broadcast, the secrets of the Fire Birds are revealed one by one. Barbaros learns that the Firebirds are aware of both Bahar Eyüboğlu's murder and Lara. Barbaros takes action to reunite Gülayşe with her father and makes his first move. He arrests the Firebirds. Now the Firebirds are against Barbaros Tunalı, the commissioner! It's time to reckon with all sins!

Will Hacer Eyüpoğlu take Gülayşe to her father? The time has come for the Firebirds to face their greatest fears, which they have been running away from for years. Gülayşe is now in front of her aunt Hacer Eyüboğlu. Hacer looks into the eyes of her niece Lara, whom she has not seen for years. Will Hacer, who learns about all the schemes that Mercan and Zıpkın have made to enter the mansion, take Gülayşe to her father? The Firebirds are really facing losing Gülayşe! How will Barbaros protect Gülayşe when all this is happening?

Sabit throws himself in front of a truck due to the pain of losing Gülayşe and everything changes. The great anger of the Firebirds causes Hacer to take a step to understand both them and the past. Panicked when Barbaros discovers Menderes, Çatal decides to tell Barbaros that he is his son. Shaken by Gülayşe's untimely declaration of love, Barbaros cannot bear to continue lying to Gülayşe and begins to tell her the truth. The first step is to say you are a cop.

While Gülayşe has trusted someone other than the Firebirds for the first time in her life, she has a hard time coping with Barbaros turning out to be a police officer. Barbaros openly confesses his love to Gülayşe for the first time. Gülayşe is very shaken by what she hears. Barbaros begins to open the secret file of Bahar Eyüboğlu murder with new information. The circle becomes narrower for Ali. The recording in the hands of Naz and Menderes will also pull the strings on Ali, but if Menderes is to be punished, Ali is willing to get burned himself and goes after that recording.

Learning that it was his own mother who took the girl he loved from her mother's bosom and kidnapped him, Barbaros maintains his composure in the face of Çatal, but as soon as he leaves there, he suffers a major panic attack. He doesn't know how to look at Gülayşe's face afterwards. Gülayşe brings Sabit and Barbaros together so that Sabit remembers Barbaros and what he has forgotten. His plan works, Sabit starts to remember what happened and tells Gülayşe.

Menderes killing Nermin changes the game for Barbaros and Ali. There is no time to hunt for evidence, Menderes must be put in prison as soon as possible before he goes any further. For this reason, Ali and Barbaros put aside their great hatred for Çatal and offer a deal. Will Çatal accept this agreement? Barbaros wants to fulfill his promise to Nizam Eyüboğlu before anything happens to him. While it is only a matter of time before they catch Menderes, the father begins to take all security measures and take steps to reunite the daughter. First he tells the facts to Nizam Eyüboğlu, and then he tells Gülayşe that he has a father who has been looking for her for years. How will Gülayşe face this truth?

Gülayşe finally reunites with her father and the father and daughter try to get to know each other. But Gülayşe's real test begins now. The secrets that the Firebirds kept from Gülayşe are revealed. Even though they knew that Gülayşe's father was Nizam Eyüboğlu, they hid this from her. This reality, which the Firebirds have feared throughout their lives, is very heavy for Gülayşe and she has to make a choice. Either his family, who raised him but hid his father, will choose the Firebirds and continue his poor life, or he will choose his father, Nizam Eyüboğlu, who has been looking for him for twenty-three years, and choose to live in the mansion of his uncle who threw him away!

To protect his daughter, Nizam Eyüboğlu imprisons her in the mansion. But this behavior causes the rebellion of Gülayşe, who cannot see her sister. Will Nizam Eyüboğlu be able to make amends with the daughter he found after 23 years? Barbaros and Gülayşe come on Nizam Eyüboğlu's radar. But Barbaros has no intention of giving up this love, on the contrary, he seeks to purify his love from all secrets. He takes his mother to Sare and withdraws from the case, and confesses to Gülayşe that it was her mother who first took him from his cradle. How will Gülayşe react to this confession? What will happen in the room where Gülayşe was born?

Naz is sure that Menderes' killer is the Firebirds. He attacks Gülayşe with the anger of losing his great love Menderes. This drives Barbar crazy. Sare takes Ali and Zıpkın into custody for questioning about Menderes' murder. He remains alone at the rest stop with his legs unable to hold the coral. Now Mercan is somewhere, Gülayşe is somewhere helpless. Unable to prevent Ali and Zıpkın from being arrested and Mercan being left alone with her disability, Barbar decides to kidnap Gülayşe. The issue of Mercan's surgery becomes more and more unresolved due to the stubbornness of both parties. While Nizam Eyüboğlu wants Gülayşe in exchange for surgery, Mercan gives up her legs to avoid giving Gülayşe.

It is up to Gülayşe to break the news of Barbaros's mother's death. Barbaros is devastated by this sad news. Will Barbaros believe that his mother committed suicide? Pamir manages to break Çatal out of prison, but Şirin's death turns Naz and Çatal against each other. But Naz has new plans that she wants to share with Çatal. Will Naz be successful? Even though Nizam is very sad about the loss of Barbaros, he comes to Naz's help. He opposes Gülayşe being with Barbaros in the absence of her mother, but the lovers stubbornly resist, and Barbaros even goes further and proposes marriage to Gülayşe. When Nizam hears this, all hell will break loose! So what will Gülayşe do? Will she choose her newly reunited father or the love of her life, Barbaros?

The Firebirds' greatest test begins now. It's back to black! Now is the time for those lost in the darkness of the past to come to light! Kara arrives, carrying all the sins of the Rootless on her back. Pandora's box opens to no longer close. Kara will turn the lives of the Firebirds upside down with the anger she has kept waiting all these years. Everyone will pay the price today for the election made years ago! Will the Firebirds be able to overcome this test or will Kara successfully take her revenge and the Firebirds will be dispersed forever? Gülayşe is like a fairy girl with her flower crown in her snow-white wedding dress, unaware that Kara is descending on the Firebirds like a dark nightmare. She welcomes the wedding guests, hand in hand, eye to eye with the man she loves, plays Harmanda, and shouts yes at the wedding table!
