Three friends, Amar Saxena, Meet Mehta, and Prem Chawla, are always chasing fun, even as their marriages to Sapna Saxena, Rekha Mehta, and Nisha Chawla weigh on them with constant frictions at home. Amar’s mother-in-law pressures for her late husband to be reborn, and she follows the guidance of a fraudster, Antakshari Baba, to keep her daughter from physical closeness with Amar. Meanwhile, Meet’s wife has a twin brother who, whenever Meet gets close to his wife, becomes an obstacle because of the brother’s imposing presence, a clash that drags in Meet’s brother-in-law (the village bodybuilder) and spirals into comic trouble. Prem’s sister-in-law—an attractive but somewhat naive young woman—moves in, insistently insisting on sharing the same room with her elder sister, which leaves Prem sleeping on the couch far from his wife.
One night, the trio meets in a bar and decides to cast off their worries and enjoy life together. They hatch a plan to travel to Amar’s village to sell off the family Haveli and, in the process, indulge in flirtations with the local women. Upon arriving, they discover the Haveli is feared by the villagers. An elderly man recounts a legend: fifty years ago, a father-daughter duo lived there, with the daughter Ragini being renowned for her beauty. Ragini died at twenty from a snake bite, yet her spirit remains tethered to the haveli, seeking a man who will share “masti” with her. The men shrug off the story, but soon encounter a striking young woman living secretly in the haveli, who is hired as their maid, and each man tries to win her affection. Ragini reveals that one man must have sex with her to release her soul, and whoever fulfills the request would meet a grim fate.
The friends become fearful and attempt to flee, but the supernatural entanglement deepens. Prem volunteers to buy them time, and they hire a male companion, Babu Rangeela, to sleep with Ragini and buy the time they need. As the situation escalates, their wives arrive at the haveli, and Ragini, angered by the ruse, turns Babu into a chicken. Ragini then forces the three men to perform bizarre acts in front of their wives and in-laws, who are secretly fasting for their long lives. Realizing their wives’ steadfast devotion, the men confront Ragini and refuse to yield to her demands. Ragini lashes out, but the group counters her with fire and calls on the spirit of Ragini’s father for help.
In a startling twist, the spirit of Babu Rangeela returns to life in spectral form and reunites with Ragini, finally satiating her hunger. Ragini and Babu depart the world together, and the three couples—now buoyed by a renewed sense of connection and commitment—live on, united and happier than before.
