This film is about a young man trapped in a top floor of a multistorey building in suburban Mumbai. Director Motwane has made a taut suspenseful film which will keep you engrossed. To justify his inability to communicate with the outside world there is no electricity in the flat, his phone battery is dead, he is the only occupant in the complex, the guard at the ground floor is partially deaf and he has not seen him go in. The film goes to show to what extent a person will go to survive. In the few days Rajkummar Rao has to drink his own urine, eat roasted bird meat and go for other desperate measures. A well made film of experimental genre. Hichcock would have been pleased to see this work.
