Tera Kya Hoga Alia

Set in Agra, Mrs. Alia Alok Parihar becomes insecure about her growing weight. She and her friend Rabiya try to keep women away from Alia's handsome husband Alok, though Alok is committed to Alia and maintains a distance from women. Alia and Alok work together in the same Hindi medium school as history and physical training (PT) teachers, respectively. Tara Kohli joins the school as an English teacher and considers Alok as only her friend but Alia becomes insecure of Tara's beauty and charm. Tara is later promoted as vice-principal of the school.

Believing that her son Rohan can foresee the future through his drawings and has a vision about her death, Alia tries to search for a new wife for Alok and a mother for Rohan. She offers the role to Tara, who is initially reluctant but becomes attracted to Alok's charm and softheartedness. Alia signs an agreement that Tara will still marry Alok if Alia doesn't die. When the prediction is understood to be about something else, Alia apologizes to Tara and Alok. Obsessed with Alok, Tara fakes amnesia, invents stories of her marriage with Alok, and bribes a doctor who asks Alia and Alok to care for her and indulge her marriage fantasy. Her mother Simran arrives from Delhi and helps her to impress Alok. Alia learns about the conspiracy but fails to prove it to Alok. Later, Tara tries to defame Alia and creates hurdles for her while both participate in the Mrs. Agra contest. Affluent journalist Rohit befriends and helps Alia, much to Alok's insecurity, and she wins the contest.

Following the COVID-19 lockdown, during which the school building became a quarantine centre, Simran's affluent friend Saudamini Sahu becomes the school principal and restructures it as an international English-medium school in a new building. All the teachers had to leave the teacher's colony and share homes, with Alia, Alok and Tara cohabiting. Alia works with the other Hindi teachers to impress the parents and school committee and save their jobs. It is decided to teach the students online. Alia struggles with conflicts from vice-principal Tara and the continuing pandemic. Later, Simran tries to legitimately marry Alok and Tara, but Alok puts a halt to it. Tara and Simran are exposed at the wedding venue and apologize. Alok and Alia are remarried while Tara and Simran return to South Delhi. During the Ganesh Chaturthi festival, Saudamini decides to close the school due to financial loss, leaving the teachers unemployed. Rohit offers the teachers the opportunity to work for a news channel, to which they agree.

Alia and the other teachers become reporters at television channel Desh Ki Dhadkan (English: Country Beat). Famous anchor Ms. Dhadkan of show Apki Dhadkan Boli (Bid Your Heart) covers entertainment, glamour and sensational stories, but Alia determines to cover important stories and show the truth.

In one of her first news investigations, Alia uncovers a fiasco and gains national praise. This results in Alia getting her own show, Carry on Alia, which soon outperforms Dhadkan's show in the ratings. Although they occasionally cooperate, Dhadkan's jealousy of Alia's popularity grows and she plots against the newcomer. When it is decided that Alia will be promoted, Dhadkan attempts to frame Alia for the robbery of funds intended for pregnant women. Alia is arrested but exonerated when her team expose Dhadkan's conspiracy with a rival television channel.
