The story begins with a funny yet unfortunate incident which forces the newlyweds, Mithi and Pritam, to return home.
They find themselves in a compromising position on their honeymoon when the validity of their marriage is questioned because Mithi refused to change her surname. She is determined not to change her surname after marriage but it doesn't sit well with her orthodox in-laws and the patriarchal society. Her decision leads to problems in her family as she faces stern opposition from her father-in-law, Pronotosh. Though Mithi's husband, Pritam is meek and quiet, he is a true liberal and respects his wife's wish. He loves Mithi and he stands by her but not at the cost of his family's peace. Her in-laws continue to call her out for her stubbornness and all hell breaks loose when Mitali, her mother-in-law, starts supporting Mithi in her stance, finding herself a comrade in the right cause where even she wants to follow suit and keep her maiden surname.
What follows is a joyful yet poignantly complex ride mixed with emotions which leaves the audience with a thought-provoking message at the end.
