What would you do if you were trapped on the 35th floor of a vacant building with no food, water or electricity? What would you do if you were right in the middle of a bustling city — one of the busiest in the world — but none saw or heard you? Watch this grim thriller to sense what it means to be trapped. Directed by Vikramaditya Motwane, the movie has the very brilliant Rajkumar Rao playing Shaurya, who convinces his lady love to diss her fiancé and move in with him. But what happens later is as absurdly horrifying as it is entirely believable. The sheer helplessness of the man and his struggle to get out forms the crux of this splendid film.
