There Was a Father

Shuhei Horikawa (Chishū Ryū) works as a mathematics school-teacher in a middle school. A widower, he has a ten-year-old son named Ryohei (Haruhiko Tsuda), who studies in the same school. While taking his class out for an excursion one day, one of his pupils drowns after running off with a classmate on a secret boat trip. Shuhei blames himself for the accident, and quits his teaching job out of remorse.
