Eşref Rüya tells the story of a young man who is a prisoner of a love whose name he does not know. Çağatay Ulusoy plays the character Eşref, who is reckless, has everything but is a prisoner of a love whose name he does not know, while Demet Özdemir plays Nisan, the young musician who makes Eşref's heart skip a beat.

Nisan, who understands that she is in great danger once again with this incident, looks for ways to escape Çiğdem's games. Eşref cannot help but be carried away by feelings that he is unfamiliar with whenever he comes face to face with Nisan. Nisan's getting closer to Eşref causes alarm bells to ring for both of them. On the other hand, a great surprise awaits İzzet, who is drunk with victory. Eşref, who is preparing to make his enemies experience hell, will also face his new rival on the security front.

After İzzet’s death, Eşref now faces an even greater enemy. Horrified by everything that’s happened, Nisan prepares to make bold moves beyond her limits in order to finally end the game. Meanwhile, with his plans progressing as intended, Kadir is willing to betray the Yetimler to eliminate Eşref from the picture. On the law enforcement side, Serdar investigates the murder at the hotel and comes face to face with Eşref and the tribe. This tense confrontation—where everything could fall apart at any moment—sets the stage for an impending major conflict. Though Nisan plans to throw Eşref into the fire to save herself, seeing a different side of him pushes her into an unexpected dilemma. Her growing closeness with Eşref is about to land her in serious trouble.

Nimet’s abduction of Nisan and Afra signals that the war between the Yetimler and the tribe is far from over. Despite Serdar’s warnings, Eşref and Nusret continue to make moves that only fuel the fire of revenge between them. Kadir does everything he can to turn the Yetimler against Eşref. Meanwhile, his unexpected encounter with Nisan sparks unfamiliar emotions in Kadir’s heart. Eşref’s bold move to rescue Afra catches Nisan off guard. Now caught in a deep moral dilemma, will Nisan be willing to stain her hands with blood—if it means saving her sister’s life?

Kadir's appearance as a rival in his deepening relationship with Nisan upsets Eşref's balance. Meanwhile, when Nisan's closeness to Eşref draws the attention of the Gürdals, Nisan faces the risk of being exposed. While Eşref is convinced to end his feud with Nusret, a surprise development leads him to burn all ships. Eşref's final move will not only cause him to throw himself into the fire, but also his loved ones. Nisan will make a move that will shake Eşref's heart in order to prevent her secrets from being revealed.

Although Nisan is willing to turn down the opportunity she has for her career for Eşref, bigger surprises await her in the future. When the Yetimler's fight with the tribe begins to disturb the elders of the underworld, an unexpected development occurs for both sides. Meanwhile, Yakup Baba's worsening condition is a sign that there will be radical changes in the Yetimler. Kadir, who is doing everything he can to prevent Eşref from coming to power, has started to get closer to Nisan. Will Kadir, who is burning with love and lust for power, be able to risk betraying Eşref, who he promised to always stand by his side? Eşref, who agreed to confront Nusret Ağa at the point where the Orphans are in danger, will cause the balances to change again with a surprise move that will have an impact in the underworld.

While Eşref tries to protect Nisan on one hand, he also tries to find the identity of the person who betrayed her. While Eşref's absence causes the team to raise the alarm, Kadir, who prepared the plot, secretly follows the events. Çiğdem enters a big impasse with the move she made against Atıf. She is ready to take big risks to continue her game. While suspicions on Kadir increase, she will do her best to hide her betrayal.

Eşref sees with his own eyes that the traitor is Kadir and begins to meticulously plan his next move. Kadir feels that the tension between him and Eşref is increasing and looks for ways to get out of the situation he is in. As Nisan and Eşref continue their turbulent relationship, it will become increasingly difficult to resist the attraction between them. When weapons are drawn against betrayal, those who want to survive will have to act quickly.

Eşref threatens all his enemies by killing Nusret. Kadir, who understands the seriousness of the situation, feels that his mask is about to fall. When the time comes to confront Eşref, he realizes that this is his last chance to put everything in order.

Although Nisan knows that there is no room for love in Eşref's dangerous world, she cannot help but dream of a future with Eşref. Eşref, on the other hand, is in shock at feeling such intense feelings for someone for the first time since Rüya. While the ceremony to be held for Eşref's ascension to power is on the agenda of the orphans, Kadir is in danger of being exposed at any moment. Helpless, Kadir will have to take refuge in Çiğdem's insidious plans. Eşref, who is in a great dilemma between his position in the underworld and his relationship with Nisan, will encounter an unexpected development that will turn his decisions upside down.

The journey he embarks on with the hope of finding the love of his life leaves him face to face with his greatest test yet.

In this great struggle where everything is turned upside down, Eşref fights with all his might to protect his loved ones. In the season finale where blood is shed, betrayal reaches its peak and the entire order is turned upside down, Eşref will face his nightmare while waiting to be reunited with his Dream.
