Yûrika plot
In Eureka, only three people survive a violent bus hijack on the Japanese island of Kyushu. The event completely disrupts the lives of bus driver Makoto and the students Kozue and Naoki. The traumatized driver disappears from view and the children are left alone in their parental home without a mother or father. They are literally dumbfounded and communicate using sign language. After two years of absence, Makoto moves in with the children. The three form a surrogate family, closely watched by student Akihiko, Kozue's and Naoki's cousin. In an attempt to finally come to terms with the violent events, Makoto buys a bus to take the children on a trip. Place of departure: the parking lot where the hostage-taking took place. During the bus trip, the three ex-hostages try to shake off their traumatic past.
