The extreme drought conditions of 1950 in AP brings a girl in front of Lord Shiva to dance in order to impress him. The girl danced for 7 days nonstop and died. It rained heavily after that and from that day it became a tradition for a girl from that family to dance every 12 years.
Fast forward to present years, Pournami and Chandrakala are two sisters who belong to the same family of the girl who danced and now the villagers want Pournami to dance but she disappears because her father tells her to get away.
Kesava, who married Pournami comes to live with Chandrakala's family and tells her that her dying sister wanted her to dance before Shiva. Chandrakala gave her body and soul to learn dancing.
