Shardul Thakur Flaglot and Suman Singh enter into a marriage of convenience but chaos ensues when her unhinged girlfriend comes to stay with them.

Shardul Thakur is a police office posted to Dehradhun, a police station for women. He is under constant pressure from his family to get married, but he isn't too keen on the idea because he's gay. Sumi (Bhumi Pednekar) works as a PE (Phys Ed) teacher in a high school. She, too, is being pressured by her family to get married but she is lesbian. She registers on a dating app where she 'meets' an attractive woman and they chat for a while. Upon meeting 'her', she finds that the person is actually a man with a fake account. He tries to blackmail Sumi, saying that he will expose her to her family if she doesn't agree to sleep with him. She goes to the police with her complaint. The person who takes down her details is Shardul. When he guesses that Sumi is lesbian, he proposes a plan: they will get married to get their families off their back. Problems arise, though, when their families continue to meddle in their lives and pressure them to have children.—alex.mjacko@gmail.com

Shardul Thakur (Rajkummar Rao) is a police officer whose widowed mother Mrs. Thakur (Sheeba Chaddha) worries about his marriage. Shardul apparently loves a Muslim girl Naaznin (Nindhi Bhati) in Dehradun and the family is willing to accept her, only so that Shardul gets married. Shardul's Taiji (Seema Pahwa), Tau Ji (Shireesh Dobriyal). Shardul is posted at a women's police station and wants a transfer, which is denied. Naaznin is a constable in his team. When the family tells Shardul that they have agreed for Naaznin, he simply says that they took very long and now Naaznin is married to someone else

On the other hand, Suman Singh (Bhumi Pednekar) aka Sumi is a 31 yr old physical education teacher who meets a person on a lesbian dating app. Priya Masi (Karuna Prakash) is trying to play match maker for Sumi with son of her Friend Kusum (Babita Anand). But Sumi scares her off by saying that she wont leave her job and that she is unlucky for boys who want to marry her. Komal (Apeksha Porwal) was Sumi's colleague at school/college, on whom she had a crush. Komal is now married and has a daughter. The person from the app requests Sumi to meet her in a cafe for which she agrees. On reaching the cafe, Sumi realizes that she was chatting with a boy all these days. Afraid Sumi leaves the place but the boy continues following her and keeps on threatening her about her sexual orientation. Fed up with his blackmails Sumi reports it to Shardul who works in a women's police station. Shardul meets Sumi and tells her that the boy from the dating app has been warned. He immediately asks Sumi to marry him, saying that he is gay himself. He wants to marry her only to get free from their family's pressure on them to get married. Sumi accepts the deal and they both get married.

They go on a honeymoon where Shardul introduces his boyfriend Kabir (Deepak Arora) to Sumi. She feels happy seeing both of them having a good bond. After returning from the trip, Shardul and Sumi move into a police quarter. Shardul preferred staying in a private colony outside the city, as nobody knew them there. The police colony in right in the middle of the city and his family as easy access to him now. Sumi gets a smaller room and thus argues to pay lower rent. Also, they don't keep a maid as its too risky. So, housework is also divided equally. Later, Sumi gets to know Rimjhim (Chum Darang) who works in a hospital (she was there to give the stool sample for her dad, who was getting some tests done). They go out on a date, where Rimjhim opens up about being rejected by her family for being a lesbian. They start a relationship immediately after, and eventually fall for each other. Eventually, Rimjhim moves into Sumi's room. When Shardul's superior's wife (DSP's wife (Durga Sharma)) questions them about Rimjhim they brush off it saying that she is their cousin. Sumi tells Rimjhim that she plans to adopt a kid outside of India. She was very attached to Komal's child (Komal had come to Sumi during her pregnancy and took her help for the entire duration), but she took her away when her husband demanded her to return to Delhi.

Rimjhim does not like that Sumi plays along as Shardul's wife in front of his police colleagues. They have a huge argument over it. Meanwhile, Shardul gets to know that Kabir is just passing time with him and is not really in love with him. He feels devastated and days pass when he finally finds Guru Narayan (Gulshan Devaiah), a queer lawyer (his exact sexuality is left ambiguous and up for interpretation throughout the movie). He immediately takes a liking to Shardul while the latter is controlling the mob during a gay marriage. They both like each other and start dating shortly after, post a period of casual flirtation.

Later, Shardul and Sumi go to Shardul's home for their first Diwali. When questioned about her not being pregnant yet, Shardul tells them that Sumi has some problem with her reproductive tract. They go to a checkup but the result turns out to be normal. The entire family thinks something is fishy, since Shardul and Sumi are fighting all the time. and they don't sleep in the same room, even though a room has been offered to them. Shardul's mother moves into their quarters to make sure that they have a physical relationship. Shardul and Sumi ask Rimjhim to move out for the time being. Despite trying all tricks, there is no luck. When Sumi suggests adoption, Taiji asks Shardul's mother to talk to SUmi strictly. While talking about this, Sumi tells her mother-in-law that Shardul is firing blanks. Since the test is done in Rimjhim's lab, she controls the results and reduces the count. Listening to this, Shardul's and Sumi's family advises them to adopt a baby for which Sumi feels so happy as that was her dream. Done with her work, Shardul's mother leaves for her home but returns back as she misses the train only to see Sumi and Rimjhim being intimate. She tells this to both the families and knowing this, Shardul asks Sumi to not reveal his sexual identity. Sumi's family (Mrs. Singh (Loveleen Mishra) & Prem Singh (Nitesh Pandey)) admonishes her for being that way while Shardul's family is furious with Sumi for being a lesbian. Shardul then confesses to his family that he is gay in a show of solidarity. His mother accepts the fact which Shardul shares with Sumi with great joy.

Sumi and Shardul decide to get divorced but Shardul receives a message stating that their adoption plea is accepted and conveys the same to Sumi. They slip off the idea of getting divorced and decides to adopt a baby and lead a life in the way they wanted, thus reclaiming lavender marriages. One year later, Shardul and Sumi adopt a baby and perform an adoption ritual in which Rimjhim too participates as Sumi and Rimjhim are going to be the parents of the baby. Shardul's superior (DSP (Abhay Joshi)) and his wife visit their home for the ritual seeing which Rimjhim leaves Sumi's side. Seeing this, Sumi's father tells Rimjhim to continue the ritual stating that the ritual needs the mother's presence. Shardul too invites Guru Narayan to accompany him in the ritual. The superior remains confused seeing this, but the four smile vibrantly.
