Pouranami is Prabhudevas's Second movie after Nuvvuvasthanante Nenoddantana as a Director.Once upon a time, may be three centuries ago, there was a village that was severely hit by a famine. A danseuse from a traditional family comes forward to dance in Lord Shiva temple for rains. Since then it has become a tradition that a girl from that particular family should dance in Shiva Temple on Pournami day for every 12 years. During 1960’s it is the turn of Pournami (Trisha) to perform the sacred ritual and she goes missing a few months before the D-day.
Siva Kesava (Prabhas) arrives in that village and attracts Chandra Kala (Charmme) – sister of Pournami. The local Zamindar (Rahul Dev) lusts for Chandra Kala. Siva Kesava convinces Chandra Kala and her father that she could perform the ritual on Pournami. But, Siva Kesava’s past catches up with him. The rest of the story is all about how the dance performance ritual at the temple takes place.
