In London, four years into their marriage, Tanu (Kangana Ranaut) and Manu (R.Madhavan) visit a mental rehabilitation center where they start bickering with each other. Because of Tanu's various allegations, Manu gets enraged, and is later taken by the doctors into custody who are suspicious about his mental health. Tanu's friend Payal (Swara Bhaskar) calls her from India and tells Tanu that she has given birth to a baby girl. Left alone to her own devices in cold and uninviting London, Tanu decides to return to her hometown, Kanpur. While leaving London, Tanu rings Manu's friend Pappi (Deepak Dobriyal) in Delhi and tells him to immediately leave for London and release Manu.
