太陽を盗んだ男

A misfit high school science teacher (Kenji Sawada, a Japanese pop singer) builds his own atomic bomb and uses his science class to work out some of the details. At first he is an accidental hero when he helps save his students from the clutches of a school bus hijacker. But after his bomb is constructed the teacher holds the government ransom. Among his demands are allowing the Rolling Stones into the country for a concert (they were banned because of drug use) and televising baseball games without commercial breaks. Meanwhile a police detective (Bunta Sugawara) tries to track him down. (In Japanese language, with English subtitles).
