The Tohoku Shinkansen Hayabusa No. 60 train departs on schedule from Shin-Amori to Tokyo. The conductor, Takaichi, welcomes the passengers as usual. A phone call then comes into the Shinkansen General Operation Control Center. The caller reveals that a bomb is placed on the Hayabusa No. 60 train and if the train's speed drops below 100 km/h, the train will explode immediately. The caller demands a 100 billion yen payment to disarm the bomb. Conductor Takaichi, passengers, and railway workers work furiously to prevent an extreme explosion.
