La Recta Provincia

A man lives with his elderly mother and works as the caretaker of a large country house in Chile. One day he finds a bone in the garden. The bone appears to have holes in it and would seem to be a flute. The man plays it. The music from it turns into a song and the voice singing the song begs the man to look for the other bones of a body that have been scattered. So the man and his mother set off to look for more bones so they can put the skeleton back together and provide the individual with a proper Christian burial.
