Hayabusa 60 (5060B) is an E5 Series Shinkansen bound from Shin-Aomori to Tokyo, under the supervision of first-line manager Kazuya Takaichi. Shortly after the train’s departure, an anonymous caller contacts the JR East headquarters in Tokyo, saying they have planted a bomb on the train that will explode if it slows down below 100 km/h. After the bomber proves their claim with the destruction of freight train 2074 at Aomori-Higashi, JR East orders all trains on the Tōhoku Shinkansen stopped to clear a path for Hayabusa 60, whose driver Chika Matsumoto is ordered to pass through all stations and stay above 120 km/h, while keeping the bomb a secret to the passengers.
Back in Tokyo, the bomber calls again and demands a ransom of ¥100 billion from all citizens to Japan in exchange for the lives of those aboard Hayabusa 60. Under orders from the government and JR East, Takaichi announces the bomb emergency, causing several passengers to question the staff’s inspection procedures while female politician Yuko Kagami uses the situation to restore her tainted reputation. As chief cabinet secretary Suwa discloses the bomb situation to the public and says the safety of the passengers is the government’s priority, the bomber hacks through all networks and streams a ransom video of the bomb being planted, causing panic aboard the train. A problem arises when a southbound train stalls at Morioka due to a bird strike, prompting JR East to switch Hayabusa 60’s route to the northbound track. With dispatcher Yuichi Kasagi’s calculations, Hayabusa 60 manages to switch tracks but hits the rear car of a northbound train. Onboard, millionaire influencer Mitsuru Todoroki streams himself and announces an online platform to raise the ransom money, prompting the passengers to share the link and make donations before Kagami confronts him.
