Macho Mustanaa is a 2012 Bengali action and romance film directed by Reshmi Mitra and produced under the banner of Remac Filmz Production.

[1][2] The film commences by showing a happy and united family, consisting of Nabab, his father, grandfather, elder brother and sister-in-law (who was pregnant).

Since that incident, Nabab's life faces a turn as he is accused of false charges and sent to jail.

He kills Nabab's elder brother and grandfather, paralyses his father, and finally, his sister-in-law lost her unborn child.

The events that occur next, i.e., through which Nabab gets back Diya and takes revenge on Bidhan Chattoraj, form the climax of the story.
