[1] The film stars Kartik Aaryan and Kriti Sanon with Aparshakti Khurana, Pankaj Tripathi, Vinay Pathak and Alka Amin playing supporting roles.

[5] Set in Mathura, it is about a television reporter who cohabits with his headstrong intern and chaos ensues when their traditional families assume them to be married to each other.

[3][4] Vishnu Trivedi, a failing politician in the small town of Mathura, campaigns to ban live-in relationships, seeing them as a disgrace to the Indian conservative culture.

Guddu and Rashmi, realising that the family would willingly accept a marriage but not a cohabitation, do not admit the truth.

Once his family, too, catches up, Guddu reveals to Vishnu that the main reason for his loss in elections is his reluctance to change; since the majority of the voting group is the young generation, which believes in modernity, opposing the youth's methods would equal lack of support from them.

He successfully convinces Vishnu to stop opposing live-in relationships and finally marries Rashmi with his blessings.

The story ends with Guddu and Rashmi covering a rally led by Vishnu, who is shown to have joined hands with Nazeem for his election campaign.
