This is a movie about the family's religious beliefs through memories. The story is based on the past events of the family. It is mentioned that 56 years ago, my great-grandfather suffered from a sudden heart attack and his life was in danger, so the elders of the family finally called on the family god, the The white water god, who helped my great-grandfather to change his life through Mediumship, and through the wishes of the descendants, they helped my great-grandfather to tide over the difficult times. The price agreed with the deity during the ceremony will also be paid by the person who made the wish at that time.
