Septuagenarian Dayanand Kumar (Lalit Behl) declares to his family, one fine night, on the dinner table that he believes that his time has come and hence he would like to go to Varanasi and pass away.Rajeev (Adil Hussain) takes his 77-year-old father Daya (Lalit Behl) to Mukti Bhawan in Benaras on his multiple requests. The two start living in a dingy room facing the Ganga ghat while Daya waits for his life to end and achieve Salvation. In the due course of time, Daya mingles with his old fellow mates over meals and hymns.Here, a person is allowed to stay for fifteen days and if he or she attains moksha by that time, well and good, otherwise, the person will have to go back home.

While Rajiv might be a stern father at home and an alert employee at his office who is always "Haan ji, sir ji, bilkul" with a smile, with his father, however, he is a different person. Here, Dayanand is the boss. Small moments between Dayanand and Rajiv, such as the one where the son walks up behind his father and waits for a piece of cake which eventually arrives after Rajiv is made to wait a bit too long or the one where Rajiv is sitting at his father's feet, cutting and giving him oranges to eat as he watches his favourite TV show. Dayanand walks up to the window in the morning and sunlight falls on his face while the birds' chirping and faraway chants of 'Ram Naam Satya Hai' envelop his mind.

One night, earlier in the film, when Dayanand and Rajiv randomly go out for a stroll along the ghats, Dayanand tells his son that he would like to be sent off with a celebration and not with sadness.Meanwhile, Lata (Geetanjali Kulkarni), Rajeev’s wife and daughter Sunita (Palomi Ghosh) visit him and Daya to Benaras. The two plead to Daya to get back home but to no avail. Soon after, Daya sends his son Rajeev back to the city and decides to reside alone in Mukti Bhawan. Soon Dayanand passes away in peace and salvation. Mukti Bhawan's final scene embraces death and celebrates departure. It teaches the viewer to part with their loved ones with a heart full of appreciation for the life they have lived and not with the pain of their absence.
