Co-Husband is related to mountain life/culture of Nepal. This film revolves around the polyandry custom prevalent among the Lama communities living in the Mountain region of Nepal. Among Lamas of Humla district of Nepal, there is still a very strange tradition, which may be a matter of great surprise to many. Lama brothers, no matter what in numbers they are, just marry a girl (have a common wife). They not only share their love and work, they also share a wife among them.
