Hideo Osumi

Inspired by a bizarre murder case, this is the story of a family and the voice "POCA PON" — a voice that sometimes heals people, and sometimes destroys them.

Haruhiko Nakayama is vice principal at a Japanese school, where he takes care of everything and dreams of finally becoming principal. But after a teacher no longer turns up for lessons, Nakayama has to teach a primary school class again after more than 20 years. He encounters such great challenges that he soon begins to doubt his profession.
