Tum is a young man who has been a monk living in a Buddhist monastery in Thailand since he was 5 years old.

But after hearing that his sister has been killed in an attack on a train by insurgents, he decides to leave the monastery and make his way to southern Thailand where his sister ran a beauty salon in a town called Betong in a district in Yala Province on the border with Malaysia.

It's only one of the many new things to the young man, who has worn a Buddhist monk's robes for most of his life.

He also encounters romantic and sexual feelings when he develops a relationship with a neighbor lady, who was a friend of his sister.

And, Tum must reconcile the feelings of hate and rage that sometimes come into his head when he thinks about Muslim people and the insurgents who were responsible for his sister's death.
