Tokuro Akamatsu (Tomoya Nagase) runs a transport company. One day, a truck owned by Tokuro Akamatsu is involved in an accident. A tire came off the truck and killed a pedestrian - a mother walking with her young son. The initial assumption was poor maintenance by Akamatsu but checks within the company found no lapses. Interestingly the company that makes and sells the truck pinned the blame on Aramatsu, aided by the police. However, the determination of the Aramatsu boss to find the truth leads him to uncovering some unsettling events. A prior accident of the same nature gave him hope and direction that something else was afoot. - edited by Buck
