Maddam Sir S01 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?
