LUKA CHUPPI is the story of a couple living-in with their family. Superstar Nazim Khan (Abhinav Shukla) gets into a controversy when it comes to light that he is living-in with his girlfriend and is unapologetic about it. The moral police come out in full force to protest against... his 'indecent' act. One such organisation is Rashtriya Sanskriti Manch and in Mathura, it is led by Vishnu Trivedi (Vinay Pathak). His daughter is Rashmi (Kriti Sanon) and she joins a local news channel after completing her media studies in Delhi. Here she bumps into Guddu (Kartik Aaryan) and both fall in love. After a fight with his elder unmarried brother Vikas (Himanshu Kohli) and brother in law Babulal (Pankaj Tripathi), he decides to tie the knot ASAP. He proposes to Rashmi. She however refuses to marry him so soon and insists on a live-in relationship. Guddu obviously freaks out. However inspired by an idea given by their colleague Abbas (Aparshakti Khurana), they decide to live in when they go on a 20-day assignment at Gwalior, where no one knows them. Hence they could live in without any fear. But in order to get the flat on rent, they pretend to be a married couple. Rashmi also has to go out wearing mangalsutra and apply sindoor. All is going well when Babulal catches them getting cosy in a public place. Assuming they are married, he tells his family about it and they all land up at their pad in Gwalior. What happens next forms the rest of the film.
