Plot

Hired to kidnap a bride, two bumbling pals get into a wacky predicament when one falls for their abductee, and the other falls for the spirit that possesses her.

Two friends, Bahura Pandey and Khattani,, work for a goon, Guiya Shakeel, where they do Pakdaai Shaadi where a bride is kidnapped and forced to marry the one who loves her. They get a job to kidnap Roohi and somehow manage to complete it--with much difficulty--but Shakeel asks them to keep Roohi at an isolated place as the marriage gets postponed. Bahura is shocked to see that Roohi is a possessed woman; Khattani refuses to believe him. Bahura falls in love with innocent Roohi, while Khattani falls for possessed Afza. When Shakeel orders them to kill Roohi, Bahura decides to go against him and free Roohi from the spirit.—alex.mjacko@gmail.com

Bhawra Pandey (Rajkummar Rao) and Kattanni Qureshi (Varun Sharma) are from Baagadpur village, where it is customary for the girl to be abducted by the man who desires to marry her. This system is called "Pakdai Shaadi" or marriage by capture. Tim (Alexx O'Nell) is a journalist who is working with Bhawra and Kattanni (who are reporters for the local newspaper Mujeerabadi Zalzala) to do a report on this unique tradition of the village. Earlier the grooms used to kidnap their brides themselves, but now they give out a contract.

Pandit (Gautam Mehra) and Riyaz (Aadesh Bharadwaj) are Guniya's henchmen who do most of the kidnappings. The village is afraid of the Mudiyapari, a witch, who keeps an eye on weddings in the village and steals the bride, if the groom falls asleep. Bhawra and Kattanni are tasked by their boss and kidnapping-gang leader Guniya Bhai (Manav Vij) to kidnap Roohi (Janhvi Kapoor) as part of a contract by a guy who wishes to marry her. Guniya also runs the printing press for newspaper Mujeerabadi Zalzala. Due to wedding season, the demand for kidnapping services is high and Pandit and Riyaz were busy on another assignment. Bhawra aspires to go to Noida and set up his own news show after having worked on 10-12 sensational news reports in Baagadpur.

However, a death in the family of the groom forces them to keep her in hiding in an abandoned woodwork shop so that the marriage can take place after the funeral. During their stay, Bhawra realizes that Roohi is actually possessed by a demonic spirit, which is corroborated by her father (Rajesh Jais). Roohi is physically very strong and has a voracious appetite. Roohi was actually supposed to be married a year ago, but the groom and his family fled after seeing she is possessed. Bhawra and Kattanni go to Guniya after taking a pic of the demonic spirit, but Guniya refuses to believe them as the pic is blurred. The duo returns to the forest cabin to find that Roohi has escaped. Bhawra finds Roohi hiding in a nearby wooden items factory. Kattanni takes Roohi to the toilet upon her request and watches her transform into the demonic spirit. Far from being terrified, Kattanni is attracted to the spirit. As Bhawra captures the spirit, she vanishes and transforms into Roohi back again.

Bhawra falls for Roohi and tries to coax the spirit from her body (he explores Shamans and priests from all religions, but finds that most of them are fake); Kattanni, on the other hand, is smitten by the demonic spirit, who identifies herself as Afza, and tries to bring her forward instead of Roohi so that he can talk to her. They learn that the demon is a Mudiyapairi (a witch with backward-turned feet who is deemed to be extremely strong) and she will not leave unless she gets married along with the girl she is possessing. And once she is married, she will take over the body permanently. Bhawra and Kattanni know that one of them will have to sacrifice their love. Both Roohi and Afza cannot coexist in Roohi's body.

Guniya Bhai, fearing the police investigation behind Roohi's kidnapping, instructs them to abandon her, but they refuse, forcing him to send his henchmen to get the job done. The henchmen, while trying to assault Kattanni, get gravely injured by Afza (one is killed and the other is badly beaten up), and report this to Guniya Bhai. Bhawra and Kattanni know that Guniya will not let this go, and they take Roohi to Chimmattipur. Guniya finds from his surviving henchman that the guys have taken Roohi to Chimmattipur.

Bhawra had met an old woman, while investigating ways to get the ghost out of Roohi. He finds out from the old woman (Sarita Joshi) that the 'Mudiyapairi' has to be tricked into marrying a man who is already married, which makes her the mistress and forces her to leave the body she is possessing. The old woman had been possessed before by the same witch, and had exorcised the spirit, but not before the enraged spirit killed her supposed husband. The old woman says that the Mudiyapari has to get married before the next full blue moon, else she would die along with the girl, whose body she has possessed. Bhawra wanted to marry the old woman, but she refused as there was a risk that the Mudiyapari would get enraged and kill the husband and wife both upon finding that she had been duped. At Chimmattipur (which is a holy and pious place for dogs), Bhawra marries a dog to trick the witch as per the suggestion of the old woman.

However, the villagers chastise him for bringing a witch into their sacred village. The thing was that all the priests of Chimmattipur had the God given gift of exorcising ghosts, but only Mudiyaparis were immune to their powers. Hence the town had banned Mudiyapari. Roohi was exposed as a Mudiyapari when she went into the village, and the priests gauged that she is possessed, and when they tried to exorcise her, Afza attacked them.

Bhawra tells the priest his plan to get rid of Afza. Guniya Bhai arrives to take revenge but realizes that Afza has to get married in less than a day. Eager to rebuild his reputation in the marriage by capture business, Guniya Bhai tells Afza she can marry the guy who had given the contract to abduct Roohi.

Bhawra and Kattanni arrive at the wedding after they learn of Guniya's plan from Tim. Kattanni, decked in Bhawra's wedding attire, convinces Afza to marry him. They are interrupted by the old lady, who tells Afza the marriage is a fraud, and deceives her into believing by showing her the video of the dog wedding. She gets confused seeing Bhawra in the groom's attire (where his face was covered) and mistaking him to be Kattanni. An enraged Afza commands Bhawra to marry him but is stopped by Roohi. Roohi then decides to marry Afza herself, thereby embracing the strength Afza had given her rather than treat her as an enemy.

Roohi and Afza accept each other and leave Bhawra and Kattanni behind. When the police arrive with Roohi's father, they are told by the old woman that Roohi has run away with herself, but the old woman disappears, indicating that she might have been helping Afza all along as she herself had married "Mudiyapairi" in the past.
