Miracle of the song

A teacher has arrived in Lansat village teaching about the God of heaven and not the devils that the villagers are used to. Damin, one of a widow's two sons, goes on a trip to clear forest for rice paddies, but a few later, he falls dangerously ill. Soon, his younger brother Pala is ill too. The widow consults the village witch doctor, but after paying the witch doctor with everything, the two boys are even sicker. The teacher who teaches about God charges nothing and is kind. Can the teacher's medicine and the believers' prayers save the lives of the two boys and win the hearts of small family and the villagers?
