Praveen Tewari, a Bank watchman, resides in Kolkata with his wife Shikha and daughter Tukai. His salary is usually stalled for months like a number of government employers. When the Corona pandemic emerges, everybody is buying and wearing masks, except Praveen. He simply denies wearing one, and regularly finds various propagandas from a YouTube channel. He has been so extensively tortured by the people nearby that he even dreams of people forcing him to wear a mask. The story takes a twisted turn when he gets into an argument with a customer which ultimately leaves him jobless. Broken and dejected by the family and society, Praveen turns alcoholic along with a bus conductor who eventually denies providing him more alcohol unless he wears a mask. Haunted with the desire to consume more alcohol, he puts on his mask.
