The plot involves a king who wants his vav (Stepwell) be filled with water. To get the water, a batrish lakshano (person with 32 qualities) needs to be sacrificed. Unfortunately, that kind of person is among the Mahyavanshi. The Mahyavanshi put up a resistance to give the kid up, but then they have to give up the kid for the sacrifice.
The film won critical acclaim when released, though more for its format than the story.
