In a quaint village, a group of women sneak away in the early hours to relieve themselves in the open, hidden by the foliage. In this backdrop, we meet Keshav (played by Akshay Kumar), who faces an unusual predicament. Due to his father's superstitious beliefs, Keshav must partake in a ceremonial wedding with a buffalo, a tradition upheld by his father, Pandit Vimalnath Sharma (portrayed by Sudhir Pandey). This bizarre ritual is believed to bring Keshav better fortune.
Enter Jaya (played by Bhumi Pednekar), the state’s top student, who initially clashes with Keshav. A chance meeting on a train leaves Keshav smitten with Jaya, but his lack of English skills and her intellectual prowess create a rift. He runs a bicycle shop and serendipitously discovers that Jaya is his customer. In an attempt to boost his business, he uses her photos for promotional posters, igniting Jaya's outrage when she finds out.
In an effort to win her affection, Keshav awkwardly tries to get close to Jaya during Holi, but she rebuffs his advances, insisting they come from different worlds. Heartbroken, Keshav vows to move on, yet Jaya finds herself strangely drawn to his sincerity. As they gradually begin to date, Keshav's father's belief that Keshav can only marry someone with two thumbs complicates their relationship. Ingeniously, Keshav provides Jaya with an artificial thumb, which she wears as a ring, fooling his father into approving their union.
However, on her first morning at Keshav's home, Jaya's frustrations mount when she is forced to once more venture into the fields for a bathroom. Having experienced a life with proper sanitation in her own village, she insists that Keshav construct a toilet, which he tries to postpone. Despite Keshav's temporary fixes, such as leading her to a train station restroom, Jaya’s insistence on having a toilet is unwavering, eventually resulting in her moving back to her parents' home out of desperation.
The plot thickens when Jaya files for divorce, citing the lack of a toilet as her main reason. The absurdity of such a case grabs public attention, prompting government officials to take action for toilet construction in Keshav's village. Yet, Keshav's father remains obstinate. A pivotal moment occurs when Keshav's mother injures herself on the way to the fields, leading even the father to acknowledge the pressing need for sanitation.
As the divorce hearing approaches, the judge receives a notification from the Chief Minister's office urging him to delay the divorce, as construction of new toilets will commence immediately. In a heartwarming turn of events, Keshav and Jaya leave the court hand in hand, and Keshav’s father extends an apology for his earlier rigidity. The film wraps up with scenes of villagers eagerly awaiting their turn to use mobile toilets, symbolizing a significant shift in the community's values and the impending construction of proper sanitation facilities throughout the village.
