Lembayung, a supposedly idyllic Indonesian hospital, became a battleground for the sanity and lives of two ambitious and determined intern, Arum and Pica. Their dream of completing their internship at Lembayung, a prestigious institution, seemed within reach, but it would soon be derailed by a malevolent force that would test their resolve and courage. Their nightmare began when they stumbled upon a mysterious woman, who was believed to have taken her own life by hanging in the hospital's bathroom. This seemingly unrelated event sparks an unassuming sense of unease, but it would be just the beginning of their ordeal. As they begin to unravel the threads of this tragic incident, they start to notice a peculiar correlation between this woman's death and a series of inexplicable events. Equipment goes missing, strange noises echo down the corridors at night, and disembodied whispers are heard in the dead of night. The usually tranquil hospital environment starts to take on a menacing aura, plunging Arum and Pica into a maelstrom of fear and confusion. It becomes increasingly clear that the mysterious woman's presence continues to exert a sick influence, her malevolent spirit threatening to disrupt the harmony of the hospital. As they dig deeper into the truth behind the woman's death, they face resistance from their colleagues and even the hospital administration. Arum and Pica's situation becomes more precarious, as they unintentionally cross paths with forces they have no control over. Events escalate to a point where they're forced to seek outside help, only to find that they're no better off. Their frantic attempts to find a solution lead them to investigate the woman's past, piecing together fragments of information to expose a dark and sinister truth. Each new discovery fuels their determination to uncover the whole truth, but unobtrusive circumstances sow seeds of distrust between them. They begin to doubt each other's perceptions and motivations, inadvertently sabotaging their fragile bond. Matters take a fateful turn when Arum and Pica confront some sort of unacceptance from the close people around them. Uncertainty seep into every fibre of their lives, leaving them questioning their own reality. Faced with increasingly overwhelming odds, the two interns struggle to persevere in a cruel and often merciless environment. While society holds up Lembayung hospital as a place where the needy are cured and lives are saved, it's beginning to unravel a nightmare - the frightening aspect of Arum and Pica's mission became clear.
