In a quiet corner of a bustling city, a modest hospital becomes the backdrop for a story that blends everyday routine with an undercurrent of unease. The corridors echo with the soft murmur of patients and staff, while the world outside moves on obliviously, hinting at hidden depths beneath the ordinary. The tone is intimate yet unsettling, inviting viewers to feel the weight of what is known and the pull of what remains concealed.
At the heart of this world is Sanjeev, a disabled receptionist whose days are marked by routine care and gentle responsibility.

Spoilers ahead
Sanjeev is a disabled hospital receptionist who is married to a nurse Pallavi and father to a daughter Amrutha. After being found injured in a forest about 59 km from Hyderabad, he is admitted to the same hospital and begins to piece together a life that feels strangely familiar, all while grappling with memory gaps that refuse to fade. He clings to a quiet hope of normalcy, yet his nights are haunted by a recurring dream: a dark, silent room where an unknown figure conducts brain surgery on a shaved patient, and the image lingers long after waking.
In parallel, Officer Vishnu of the Preventive Crimes Unit is assigned to a troubling wave of missing children—mostly orphans and runaways. The only solid lead is a CCTV clip showing a hooded man and a dog snatching a child from the highway in the pre-dawn hours. A local newspaper reporter who witnessed the incident helps Vishnu draft a sketch of the suspect, narrowing the field but leaving the case open to possibilities that stretch beyond a simple abduction.
Driven by a thirst to understand who he really is, Sanjeev leans on his friend Yasir, who uncovers a striking clue: a photograph in a book about India’s Emergency era depicting a lookalike of Sanjeev from more than three decades ago. The trail leads them to Ashwatthama, a student leader once linked to a bombing of a police station and never located. A further chat with an old acquaintance of Ashwatthama reveals that the last person known to have seen him was his former girlfriend Amrutha. Yet when Sanjeev presses on with the search, Pallavi chides him for risking their family’s safety by chasing a past that she fears could disrupt Ammu’s world.
The investigation takes a dark turn when the police sketch appears to match Sanjeev himself, and Vishnu arrests him on the spot. Pallavi and Yasir, however, reveal a crucial truth: CCTV footage from the hospital at the time of Ammu’s kidnap shows Sanjeev’s alibi, clearing him of involvement. Before relief can settle in, a new threat emerges—a man who looks exactly like Sanjeev abducts Ammu from her school, forcing Vishnu to redouble his pursuit and casting doubt on the family’s safety once more.
Sanjeev consults with the now-older Amrutha, who shares a startling memory: the last time she saw Ashwatthama was decades ago, when he told her he was headed to his brother’s house. This clue points Sanjeev toward a remote forest house, where he confronts the source of his dreams—the dark room filled with several tonsured patients on whom brain surgery had been performed. Through the recovered memories, he discovers a brutal truth: he is Ashwatthama, who fled to conceal a terrible secret within his family. Ashwatthama’s brother Arjun—a physician obsessed with the pituitary gland and the possibility of halting aging—had perfected a form of immortality on himself and his sibling but failed to replicate it in others.
Armed with this revelation, Sanjeev learns Ammu, being the offspring of the immortal Sanjeev, holds the key to amplifying the process. The pursuit escalates when Vishnu closes in, but Arjun intervenes and kills Vishnu, aiming to seize Ammu for his own experiments. A furious confrontation ensues; Sanjeev fights Arjun, defeats him, and sets fire to the house, burning Arjun’s research and rescuing the other kidnapped children in the process. The blaze marks a brutal end to a dangerous quest and marks the city’s return to safety, at least for now.
In the aftermath, Inspector Yuvraj, who had aided Vishnu, informs Sanjeev that the property once belonging to Arjun is now a clue in the case, and asks if Sanjeev knows who the man behind the mystery is. Sanjeev chooses to guard the truth, claiming no recollection of the past, but Yuvraj recognizes echoes of a family name in his records that align with Arjun’s history. A final press conference is held to address the events, while a scarred and burning Arjun watches from the shadows—carrying a file on Ammu and a determination to complete his research at any cost, leaving open the possibility that the pursuit of immortality may not be over.
