Shôwa hayari utata: Jealousy (1991)

International scholar Kenzo Ishikawa is calling for environmental protection and ecology awareness on a stage. However, the audience is small and the reaction is not good but one man called Haruo was listening enthusiastically. They both meet again at a bar where Ishikawa continues his ecology speech. Haruo wanted to hear more from Ishikawa and visited his house where they embrace after disposing of clothes they deemed harmful for the environment. To further protect the environment Haruo wants to blow up a disposible chopsticks factory and he prepares to make a bomb but Ishikawa doesn't agree with him.
