Set parallelly in the 1990s and 2019, Chhichhore tells the story of Aniruddh "Anni" Pathak, a middle-aged divorced man whose son Raghav tries to commit suicide after failing to clear the JEE entrance examination, and who, despite survival, is unwilling to live due to the fear of being branded as a "loser", which makes a desperate Anni recount his own experience to Raghav of his own time at college, wherein he and his five friends too were called 'losers', and how they managed to remove that 'tag'; as he continues along to narrate his story, the other five join their friend and complete the story.

Principal photography commenced in September 2018. Chhichhore was released on 6 September 2019, receiving widespread critical and commercial acclaim for its direction, storyline, dialogues, humour, performances of the ensemble cast, social message, and portrayal of hostel life in Indian colleges.
