Ali Fazal plays the role of Kabir who is in love with Rachna (Anisa Butt). His task ahead is to seek lady lover's hand in marriage by seeking the approval of her brother Professor Laxmi Nivas (Gulshan Grover).
On the other hand we see Ali Fazal in another avatar. That's because he plays a double role in the movie. In the new avatar, he plays a goon named Rasiya Bihari. This goon is hired by a don called Razzak Khan. The don is real estate king and his goal is to get Laxmi Nivas vacate his apartment and that is why he hired the goon. If you think that this explanation of the plot is complicated, watching the film is worse. It's far more chaotic on screen.
There is the presence of the romantic element in the first half of the movie but post interval, the film is dragging and we just wait for the movie to end. Baat Bann Gayi had certain situations in which there could have been some hilarious moments but the makers have failed to explore it. One thing that shines in the movie is the actor Ali Fazal. He does his part of the job with a natural ease.
