Dehraadun Diary is a love-story between the rich and poor - laden with political power-play, corruption, a feudal society and a manipulative social system. Preeti (Ragini Nandwani), daughter of the Thakurs who boast of political power and clout, is in a relationship with Anshul Sharma (Rohit Bakshi). While his family has blessed the jodi, the Thakurs are far from embracing this luv-shuv-shaadi.

Preeti's hot-headed brother Vishesh (Vishal Bhonsle) is outraged on spotting the two at a wedding, and all hell breaks loose. Anshul has surreptitiously whisked away and brutally murdered. Enter the victim's brother, Akash (Adhyayan Suman), who is ready to forego his future to fight for justice - over 8 long years! Having lost their young son, the parents of Anshul, Mr. and Mrs. Sharma are there confronted by the corrupt system. They can't match steps with Thakur's political powers and ways to shield his son. However, encouraged and supported by Anshul's younger brother Akash, the old couple makes a resolve- to fight, fight till they get justice.

So, the film is the journey of the mother who has lost the child she once held in her hands and dreamt of an old age holding his hands. It's the journey of a brother who could have focused on his career, his future, yet decides to give it all up so that never again a brother loses his 'bhai' to an act of rage. It's also the journey of a soulmate who loses herself after the loss so much so that she takes any path she is guided to. Even turns supportive of her own brother when faced with legality but at the end, the unadulterated power of love brings her to the threshold and she stands for the right
