The show is set in Delhi, and revolves around Siddhant Sinha and Anushka Reddy.
Anushka Reddy, daughter of Telugu industrialist Krishna Kanth "KK" Reddy returns home after spending seven years in the US. Siddhant Sinha is a budding lawyer, belongs to middle-class Brahmin family from Bihar, and is the son of lawyer Prabhakar Sinha who was KK's legal advisor, right-hand man, confidante, and best friend. Siddhant and Anushka are childhood friends, who broke up seven years earlier due to misunderstandings.
Siddhant’s father, Prabhakar, supports KK in both business and personal matters, partly out of gratitude for help he received from him 18 years earlier, as well as their long-standing friendship. Siddhant later joins his father at the Reddys’ company, where Anushka works as the head of Human Resources.
When an accident occurs at a rival company owned by Sumit Goyal, he accuses KK’s company of sabotage, alleging it was intended to recover a lost deal. Although the investigation clears KK’s firm of wrongdoing, Prabhakar remains suspicious that someone influential may have been involved. While attempting to uncover the truth behind the incident and the deal, Prabhakar dies; doctors attribute his death to sudden cardiac arrest caused by acid reflux.
