2 families, a brother each, are taunted because of their sexuality and a sister is turned on by one. Revenge is sweet when both brothers can give the bully a taste of his medicine, and the sister can just have a taste.
Karen hasn't seen her sister in many years and she is both shocked and excited by what she has become. Po is now a girl with little understanding of normal standards of decency. But Karen is determined to be a good example to her wayward sister.
What runs in the family.... when girls come of age, they are supposed to uphold taboo that is in fact the essence of the village culture. So the mother sends her daughter to their roots, the village of Paankpara; where the girl will get initiated and emancipated- as a complete woman.
