The premiere of Graveyard Season 2 kicks off with a lush garden party hosted by Fikret Sadoglu, a figure intricately woven into the fabric of the police department. Among the guests, Yasemin, the daughter of the caretakers, shares her passion for detective narratives, her voice tinged with a hint of longing. However, her romantic life is anything but fascinating as she finds herself in a heated dispute with her gardener fiancé, Rustu, who reassuringly yet condescendingly asserts that no one else would marry her.
Reluctantly, Onem attends the festive gathering accompanied by Feriha, under Chief Haluk's directive to curry favor with the influential elite to bolster her campaign for leading the Special Crimes unit. Meanwhile, her team doggedly pursues the case of Seher Duru's murder, only to hit a roadblock when their sole suspect, Sermiyan, is cleared due to a mismatch between his gun and the murder weapon. Serdar is overwhelmed by stress, while Seher's father, Hasan, considers abandoning their seemingly futile quest. The net tightens around one remaining potential suspect: Seher's brother, Mert, though the final decision rests solely with Hasan.
At the party, Fikret's youngest son, Yasar, the black sheep of the family, continues to stir up trouble, his actions a stark contrast to his polished brother Tolga's charm. Fikret, meanwhile, flirts subtly with Onem, adding a layer of intrigue to the evening. The atmosphere shifts abruptly when Yasemin is discovered dangling from the ceiling, six months pregnant and bearing self-inflicted wounds on her wrists. In a dramatic turn, Feriha performs an emergency C-section, miraculously saving the baby's life.
Chiefs Haluk and Ozkan swiftly usher the guests out and allow the Sadoglus to depart, hastily branding Yasemin's death a suicide. The prosecutor, however, reasserts some authority, mandating an autopsy by Feriha and a thorough search of the premises by the police. Preliminary inquiries reveal that Yasemin's parents, Nermin and Murtaza, were unaware of her pregnancy; she had seemed perfectly fine, immersed in her college studies.
This retelling paints a vivid picture of the intricate web of relationships and the dramatic twist that unfolds at Fikret Sadoglu's garden party, setting the stage for a season filled with suspense and revelation.
Berk and Serdar engage in a heated dispute over her computer password, eventually overcoming the obstacle. She was once an avid reader and writer, her final testament being Orhan Veli's poignant poem titled 'Suicide.' Delving deeper into Rustu's background reveals him as a former weightlifter who was blacklisted for his steroid use. However, their efforts to apprehend him are thwarted when Ozkan provides them with a misleading address.
Onem finds himself puzzled, but Serdar is in the know, thanks to his father's friendship with the Sadoglus. For years, Ozkan has been shielding them, a protective umbrella that first opened when Fikret committed a homicide and Ozkan tampered with evidence. Onem and Serdar stumble upon Ozkan enjoying a round of golf with Fikret, leading to a tense confrontation marked by subtle aggression. Ozkan claims Rustu is a distant cousin of Fikret's, having met Yasemin seven months prior and falling deeply in love. Yet, Onem can't shake the feeling that she appears unhappy in their engagement photos.
During the autopsy, Feriha makes a startling discovery: Yasemin lay on the ground for fifteen minutes after her demise. This indicates that she was hanged to falsely present her death as a suicide. Selin, Sofia's replacement, tracks down Rustu's actual residence but finds nothing incriminating. Instead, Rustu arrives at the morgue unexpectedly, demanding to take Yasemin's body and displaying signs of aggression. Feriha narrowly prevents him from carrying out his wish before Onem bursts in. The chaos he leaves in his wake reveals footprints matching those found at the crime scene.
Furthermore, Yasemin's writings exude a sentiment that true love should never be coerced. As Selin analyzes these writings, Serdar mocks her relentlessly. Her analysis concludes that Rustu raped and murdered Yasemin after she rejected his advances.
But Serdar, with a gleeful twinkle in his eye, remarks that the unwanted consequence of steroids is infertility—a tidbit that doesn't escape his notice. However, just as he's diving into this revelation, Onem interruptions, pulling him away from his interrogation and scolding him for unloading his frustrations onto Selin. Taking the reigns, Selin guides them through a startling discovery: Rustu harbored feelings for Yasemin, even knowing the child wasn't his. Following a heated dispute, he sought to mend fences, hence his footprint's presence. He reveals that a month and a half prior, the Sadoglus recruited him and orchestrated his marriage to Yasemin. Yasemin, believing no one would accept her child, called off the engagement. Ozkan, enraged, gave Yasemin an ultimatum—marry or abort. CCTV footage from the gynecologist's clinic a week ago captures Ozkan forcing Yasemin inside, but she flees within ten minutes. The officers deduce that Ozkan must be shielding the true father's identity, casting suspicion on Fikret and his sons. Meanwhile, Serdar pleads with Hasan to intervene with Mert on behalf of Seher.
That evening, Onem's daughter Sude releases her maiden episode of a true-crime podcast with her buddy, Can. Onem beams with pride but can't quite shake her curiosity about Can. Sude, sensing her mother's scrutiny, becomes defensive and storms off in a huff.
Back at the precinct, Selin notices the uncanny resemblance everyone draws between her and Sofia. Yet, Onem offers solace, urging Selin to embrace her unique self.
Returning to the crux of the matter, Haluk is compelled to involve Ozkan upon reviewing the CCTV footage. Ozkan asserts ownership of the child but balks at the suggestion of a DNA test. With a warrant in hand, he finds himself with little choice but to comply. Meanwhile, Onem delves into the mystery surrounding Lale, a female employee who tragically "fell" to her death at Sadoglu Holdings five years prior. She suspects that Fikret had an affair with Lale, culminating in her murder, with Ozkan orchestrating the cover-up. As Onem confronts Ozkan in front of the precinct, he attempts a hasty exit.
Later, Onem visits an art exhibition curated by Lale's sister, who immortalizes the stories of murdered women who were never granted justice through her paintings. However, she expresses fierce disappointment in Onem for pursuing the case five years too late.
With this lead exhausting itself, Serdar and Onem turn to Yasar, a close friend of Yasemin's. He harbors a desire for revenge against his family, despite their intimidating presence. Regrettably, Tolga makes an unwelcome appearance, and Serdar's attempts to provoke him fall flat.
The first episode of Graveyard Season 2 concludes with a chilling scene: Ozkan phones Onem, addressing her as his child and offering her his "old car," professing his love. Sensing the gravity of the situation, Onem rushes to him. Yet, upon her arrival, she discovers that Ozkan has taken his own life, leaving behind an apology note.
