S1·E115 The Mystery Of Naagin

Even after being hit hard the last time, the Mahila Police team persists in its hunt for the thug. They lay their trap in a location where the criminal is most likely to show up; an exhibition of a naag mani. It is conducted by a professor who claims that at exactly 12o'clock a naagin will emerge from the mani. At first, everyone is sceptical, but when a naagin does appear, it leaves them dumbstruck. Who's this naagin and what is her motive? But most importantly, where is the thug?
