Helen Paul is a B.Sc Nursing graduate and attends IELTS coaching classes intended for a job abroad. She works part-time at a restaurant named The Chicken Hub, inside a plush mall. She lives with her father Paul, an insurance agent. He is not happy about her going abroad. Paul is a conservative Christian and has disagreement with Helen associating with non-Christian friends. Unbeknownst to Paul, Helen has a Muslim boyfriend, Azhar, who is also in search of a job.
One night, on their way to Helen's home, they are stopped by police and Azhar gets fined for not wearing a helmet and drunken driving, and they both are brought to the police station. Paul is summoned to the station and is in dismay of seeing his daughter and does not talk to her despite her several attempts. The following night, after work at the Chicken Hub, Helen's manager Jayashankar unknowingly locks her in the freezer room. At -18 °C, Helen has to survive in the freezing cold and tries everything to keep herself alive. She tries to block the evaporator fan but ends up dislocating her leg. She starts to get frostbite and begins to bleed through her nose.
Her father starts getting worried that Helen has not reached home. He searches for her with the help of his neighbour. They call all her co-workers but they do not know her whereabouts. Azhar, who was half-heartedly on his way to Chennai, returns and joins the search. They go to the police station to file a complaint and are greeted by the SI, Ratheesh Kumar whom they had met the day before. He suspects Azhar. Paul tries to defend him, and this causes a feud between the sub-inspector and the search party. He deliberately tries not to help them by not sharing the last tower location of Helen he obtained from the cyber cell.
They get a hint that Helen might have had a problem with the auto drivers in front of the mall and they all arrive at the mall to enquire. The auto driver whom they suspect denies any wrongdoing. At this point, they meet a watchman of the mall who says that Helen might not have left the mall because he usually notices her going in and out. They rush to the Chicken Hub and open the freezer. After 5 hours, they find Helen. She is taken to the hospital just before she enters the last stage of hypothermia. Paul then enquires with the watchman about how he was sure about the fact that Helen had not left the mall. He says that Helen always smiled at him every time she came in and out of the mall and that he had not seen her go out on the day of her missing.
Helen reunites with her father and boyfriend. The doctor says that she is out of danger but will need physiotherapy later. He continues that its difficult for any common man or woman to survive such cold condition and that Helen was a brave girl. When the watchman asks Paul what his daughter's name is, Paul proudly replies "Helen".
