Undekhi revolves around an adivasi girl shot dead while dancing at a wedding in Manali, Himachal Pradesh, after she refuses the repeated attempts of the groom's father to act fresh with her. An outstation cameraman who records the entire event then gets caught in the deadly crosshairs between the self-entitled, toxic, murderous groomsmen, aided by the corrupt indigenous police force, unaided by his fellow, helpless video crew, and a seemingly honest cop from Bengal who, coincidentally, appears at the right place at the right time to arrest said adivasi girl's close friend, who was also dancing at the same wedding.
