Mili Naudiyal is a B.Sc Nursing graduate who signs up for IELTS coaching with the aim of finding a job abroad, specifically in Canada. She keeps up a part‑time gig at a restaurant named Doon's Kitchen, tucked inside a glossy mall, and she shares a home with her father, Niranjan Naudiyal, a man who firmly opposes her dream of leaving the country. Her personal life is complicated by a relationship with her boyfriend, Sameer Kumar, who also doesn’t fully back the Canada plan. The trio’s tensions come to a head when, one night, they are pulled over by the police for drunk driving and not wearing a helmet, and both Mili and Sameer are taken to the station. The news hits Niranjan hard, and the sight of his daughter with a man who has run afoul of the law creates a rift that keeps him distant for days. As the dust settles, Mili finds herself cutting off contact with Sameer, who shows up at her workplace to make amends but is met with a firm, final rejection.
In a cruel twist of fate, a routine closing at the restaurant becomes a life‑or‑death crisis. After work, Mili is asked by colleagues to help move some boxes into the storage freezer, and, when the lights go out and the door seals shut, she realizes she’s accidentally locked inside by the oblivious restaurant manager, Sudheer Malkoti. The temperature plunges toward a deadly −18°C, and she must improvise to survive. As fear gnaws at her, she tries to block the freezer’s exhaust, though the attempt results in a dislocated leg and alarming frostbite. The once‑thriving space around her becomes a white, silent trap, and every breath grows shallower.
Back at home, Niranjan grows increasingly anxious as night turns into a long, unnerving stretch of silence. He enlists a neighbor to help search, and they reach out to Mili’s coworkers, none of whom can confirm her whereabouts. Sameer returns from a tentative trip to Delhi when he hears she’s gone missing, joining the frantic effort, much to Niranjan’s mixed emotions. The local investigation is disheartening: Sub‑inspector S.I. Satish Rawat expresses a stubborn conviction that Sameer and Mili ran away together, brushing off the family’s concerns. The family and their supporters press for action, but Rawat and his partner’s responses feel cold and evasive, provoking growing frustration and tension.
Enter Inspector Ravi Prasad, who arrives at the station and — after scolding Rawat for his behavior — commits to redoubling efforts to locate Mili. With his arrival, the case shifts from a passive inquiry to a more coordinated pursuit, and Niranjan clings to the hope that his daughter will be found safe. Inside the freezer, Mili’s struggle intensifies as her phone buzzes with calls from her worried father, one of the few human links left in this perilous moment. She discovers a mouse nearby and, despite her worsening condition, makes efforts to protect another life even as her own strength drains away. The mouse’s quiet tragedy underscores the severity of her isolation and fear.
Meanwhile, the investigation thread grows more intricate. A Cyber Cell update reveals the last known mobile tower location tied to Mili’s device points toward the mall where she works, but Rawat delays passing this information to Prasad, feeding the sense of a stalled search. Sameer offers a new clue: an old incident where auto‑drivers outside the mall harassed Mili could have sparked retaliation, and he relays this possibility to the group. They race to the mall to question the drivers, yet one offers a credible alibi while another denial reinforces the mystery. The mall’s watchman provides a glimmer of hope, suggesting that Mili didn’t simply vanish into thin air.
In a sudden breakthrough, a metal dish tumbles from a vent above the storage area, catching Niranjan’s eye. The group rushes to the vent and traces a path back to Doon’s Kitchen, realizing the freezer’s location is the key. They hurry to the freezer, where they find Mili collapsed on the floor, her body nearly depleted of heat. She’s rushed to the hospital for urgent medical care, and the ordeal begins its slow, painful turn toward recovery.
The day after brings a fragile reunion. Mili, Niranjan Naudiyal and Sameer Kumar come together in a healing moment, and the crisis seems to draw them closer instead of tearing them apart. Niranjan offers his blessing as Mili reconsiders her Canada plans, a decision that signals a new harmony for the family. The restaurant’s operations face scrutiny as well: Sudheer Malkoti is warned to install an alarm in the storage freezer or risk losing the establishment’s license, a consequence that underscores the seriousness of the incident. The mall’s quiet witness, the watchman, recalls how Mili was the only person who always smiled at him, a small but poignant reminder of her character. In a final, quiet confirmation of who she is, Niranjan names his daughter aloud: “Mili.” The closing note leaves a sense of resolve and renewed connection, even as the city and its people move forward from a harrowing night.
