The fourth episode of Season 1 of "The Glass Dome" kicks off with the police returning to Lejla's abode to gather crucial evidence, following the revelation of Ecki's presence there. In a bid to safeguard Lejla, Valter secures all the windows tightly shut, an action that inadvertently stirs up haunting flashbacks of her confinement within the glass dome. To divert her turbulent thoughts, Lejla immerses herself in scrutinizing the evidence pertaining to her case, with Valter lending his insightful input. Together, they concoct a theory that Ecki might be behind Alicia's disappearance.
Lejla contends that Ecki's urges resemble a relentless addiction, speculating that a recent event in his life could have ignited this episode. As her mind wanders back to her harrowing ordeal in the glass dome, she meticulously crafts a profile on Ecki.
Elsewhere, the police enlist the expertise of another professional to interrogate Isla, who divulges a critical detail: Ecki bears a red tattoo or mark on his arm. Subsequently, Lejla convenes with Tomas, presenting him with her meticulously compiled profile on Ecki. Tomas, though seemingly irritated by their meddling, endeavors to listen intently to their theories. Lejla urges him to delve into past cases and ascertain whether Alicia aligns with the profile she's painted of Ecki, believing he thrives on power and is orchestrating a game of cat-and-mouse with the authorities. In response, Tomas informs her about Isla's description of Ecki's tattoo.
Post her meeting with Tomas, Lejla reaches out to a colleague in America for a fresh perspective on the case. Raul concurs with her assertion that some serial killers shy away from acknowledging their early victims due to embarrassment. This revelation propels Lejla to delve deeper into earlier cases, seeking Ecki's inaugural victim. She enlists Valter's assistance to procure the relevant reports.
Concurrently, Tomas pays Said a visit to update him on the case's progression. Said finds himself consumed by guilt, but Tomas offers him solace. On their return journey, Jorun persists in her quest to uncover Louise's lover, despite Tomas's efforts to dissuade her.
In the quiet depths of the evening, Lejla is once again visited by a vivid dream of her mother, an encounter that serves as a poignant epiphany. Driven by this newfound insight, she meticulously scrutinizes the reports and stumbles upon a crucial clue leading to another victim, Ines. Studying the crime scene photographs, she concludes with conviction that Ines was Ecki's inaugural prey, postulating that his cruel dehumanization of subsequent victims was a skill honed after that initial, harrowing act.
The following morning, Lejla expeditiously dials Tomas's number, urging him to delve deeper into Ines's case. As the hours drag on with monotonous slowness, she finds herself assisting Aino with grocery shopping at the local store. There, she unexpectedly encounters Jim, whose menacing threats are swiftly diffused by Martin's timely intervention. Grateful for his help, Martin extends an invitation for drinks later in the day, to which Lejla readily agrees.
With heart lightened, Lejla ventures towards Aino's abode, but the tranquility is shattered when Isla, in a reckless bid to lure Ecki back, pries open a window. As anticipated, the police soon descend upon Isla's residence to comb the premises. Lejla seizes the opportunity to quiz Tomas about Ines, only to discover he has scarcely glanced at the case. Desperate, she pleads for access to the archives, but her request falls on deaf ears. Sharing her hypothesis that Ecki's sole focus remains Alicia, and he has no intention of taking anyone else, Tomas dismisses her theories with a wave and departs.
Tragically, Lejla's theory is proven incorrect when another innocent girl, Emma, is abducted. Heart-wrenchingly, she returns to the haunting bridge, ignoring Valter's calls. Worried, Valter heads to the police station in search of her, only to find it eerily unattended, with Aino's absence leaving the reception desk deserted. As he listens to the voicemails, a chilling call from Ecki and Emma catches his attention. In it, Ecki taunts, revealing Emma's captivity while mockingly encouraging her to seek help from her parents.
Valter, in tandem with the police, deciphers the location of the call from the ambient noises in the background. CCTV footage from the vicinity is swiftly sourced, identifying a suspect vehicle registered to a house in Mora. Without hesitation, the police speed towards the address, hearts pounding with hope and anticipation of apprehending the monstrous culprit.
Meanwhile, Lejla and Martin find themselves at the local bar, where she orders a selection of non-alcoholic beverages. Martin, caught in the grip of sorrow, unburdens his heart to her about his sister's mysterious disappearance. Burdened with guilt for failing her, he has embarked on a nationwide journey to aid those who have vanished without a trace. As their evening draws to a close, Lejla expresses a desire to visit Martin's quaint, rented cottage.
There, amidst the cozy confines of his home, Martin unveils his intriguing theory regarding Ecki. He harbors suspicions that the recent abductions might be the ominous handiwork of a copycat criminal. Lejla, her playful side emerging, teases him about the ineptitude of such an imitator and proceeds to toast with Martin using a glass of whiskey.
Elsewhere, the police descend upon Mora with urgency, raiding the suspected perpetrator's residence. Inside, they uncover newspaper articles detailing Lejla's case, alongside some of her personal items. Valter, keeping Lejla in the loop, informs her of the latest developments and takes note of her whereabouts. He assures her of a callback once he gleans further insights.
In a grim twist, the police link the house to a man named Daniel Frick, whose name sends chills down their spines. Three years prior, Frick had attempted to kidnap a one-year-old girl and was subsequently confined to a psychiatric facility. Recently released a month ago, he has been missing ever since. A photograph of Frick is flashed before them, revealing an unmistakable likeness to Martin.
Back at Martin's snug cabin, Lejla's eyes fall upon his distinctive birthmark, the pieces of the puzzle suddenly fitting together in her mind. She attempts to rise but finds herself collapsing to the floor, her world spiraling into disarray.
