Main plot
Sanjuoy Dholakia is planning to move out with his wife Tisca and their son Aryan. He is anxious to break the news to his father Ramesh, worried how he would react. When Sanjouy is forced to reveal the truth in a game of Truth and Dare, Ramesh is overcome with sadness, and keeps trying to convince Sanjuoy not to move out. As Tisca tells Sanjouy's mother Pallavi that moving out was not her decision, Sanjuoy's grandmother, Hemlata accuses Tisca of wanting to remain in the family just to take advantage of Pallavi as a babysitter for Aryan. As Pallavi feels upset, Hemlata's husband Mansukhlal resolves the conflict, assuring Pallavi that Tisca values her.
Suresh, Hemlata and Mansuhklal's elder son, lives in the US. One day, he calls the family and reveals that he has married Kwamboka, a Kenyan-African woman, much to Hemlata's dismay. However, everybody else is excited to meet her.
Hemlata's gold jewellery, given to her by her mother-in-law, goes missing. Meanwhile, Napoleon, a famous designer, showcases a design that quite resembles one of Tisca's designs. Thus, Hemlata accuses Napoleon of stealing Tisca's design in a post on social media. Hemlata's jewellery thief is found to be their delivery man and her jewellery is recovered, only for her to find out that her mother-in-law had given her fake jewellery. On Tisca's insistence, the Dholakias choose not to press charges, since the thief has a promising future ahead of him.
Tisca freaks out when she sees Hemlata's post, confessing that she was the one who stole Napoleon's design, not the other way round. Tisca apologizes to Napoleon, but he admits that Tisca's version of his design was better than his original design. He thus offers her a job in Delhi. Sanjuoy and Hemlata are against this but the other family members support Tisca. Sanjuoy eventually comes around and admits that he felt jealous. He then supports Tisca in her temporary move to Delhi.
When Suresh and Kwamboka visit the Dholakias, Hemlata is surprised by Kwamboka's sweet nature and her values. Hemlata warmly welcomes her into the family and adores her to the extent that she ends up completely neglecting her elder daughter-in-law Pallavi. Pallavi feels insecure of Kwamboka, but when Hemlata and Kwamboka get into a fight, Pallavi supports and comforts Kwamboka, thus developing a good relationship with her.
Tisca tells Sanjuoy that she would soon be back to Mumbai, as Napoleon is shifting the company headquarters there. But instead of being happy, Sanjuoy gets worried and behaves secretively, leading Mansukhlal to suspect that something is wrong. Meanwhile, Sanjuoy's sister Ayushi tells Pallavi that she is in a casual Friends With Benefits relationship with her friend Timmy. Ayushi's encounter with a prospective groom goes horribly, as he turns out to be extremely sexist.
Tisca finds out that she is pregnant. She and Ayushi decide to surprise Sanjuoy but Ayushi catches him cheating on Tisca with Jacky, the ex-husband of his business partner Diana. Sanjuoy declares that it is not just an affair but that he loves Jacky, and convinces Ayushi to keep this a secret. Mansukhlal, who was suspecting Sanjuoy of having an affair with Diana, finds out the truth. He tells Sanjuoy to choose between Tisca and Jacky.
Pallavi has a sudden heart attack and she is rushed to the hospital. Dr Jatin, husband of Hemlata and Mansukhlal's daughter Falguni, assures the Dholakias that Pallavi will be fine but tells them that Pallavi must rest and reduce her responsibilities. The family steps in to fill Pallavi's responsibilities while she recovers, while Tisca finds out that she is having twins. Sanjuoy and Tisca tell Ramesh that they have chosen not to move out. But surprisingly, Ramesh tells them that Pallavi's heart attack taught him not to neglect himself and his own life, and that he would support Sanjuoy and Tisca whenever they wish to move out.
Sanjuoy asks Jacky to plan the party for Hemlata and Mansukhlal's anniversary. The Dholakias gather at a mall to celebrate, but the mall is hijacked by terrorists. The terrorists publicly make certain demands and threaten to kill the hostages one by one if their demands are not met within ten minutes. Everyone, certain that they are about to die, decide to play one last game of Spin the Bottle to reveal their secrets and unburden themselves before dying. Pallavi reveals that despite claiming to be a pure vegetarian, she secretly eats fish and sneaks it into Hemlata's food too; Mansukhlal and Hemlata reveal that Suresh was adopted and not their biological son; Jatin reveals that he has another wife with whom he also has a child; Falguni, in response, reveals that she had transferred all of Jatin's assets to her name; Ayushi tells Ramesh that she has been sleeping with Timmy; Sanjuoy reveals his affair with Jacky and tells Tisca that he loves him.
As their ten minutes run out, they brace themselves for death but find out that the police have arrived and that they are saved. With everyone's secrets now out in the open, everyone fights amongst themselves. The show concludes with Aryan wondering what will happen next.
