Dolly (Sonam Kapoor) is a con bride who gets into fake marriages and loots the groom on the very first wedding night. She has her notorious gang who along with her robs the groom and his family and flees away leaving them penniless. Dolly's gang meticulously researches and finds the prospective groom and the beautiful dolly charms them into marrying her only to grab all their valuables.
Dolly's first target was a Haryanvi lad named Sonu Sheravat (Rajkummar Rao) who genuinely loves her but is conned by dolly and her insane 'so called' family. The next victim is muma's boy Manoj Singh Chadda (Varun Sharma), a typical Punjabi munda who falls prey to dolly's trap. After fooling many other innocent targets, the next is the story of Robin Singh (Pulkit Samrat) who is a cop and wants to unveil dolly's truth along with the other two victim grooms. Robin has a significant connection with dolly's past and hence has his own motive to crack this case of the 'Lootehri Dulhan'.
