A late-night call brings forensic pathologist Masumi Mizusawa and MEJ director Maho Kiryu to the scene of an apparent traffic accident involving shipyard president Yasuo Izawa. However, inconsistencies at the scene quickly raise suspicions. The victim’s body was thrown too short a distance despite clear signs of sudden acceleration, and the autopsy reveals injuries that don’t fully match the evidence. As the MEJ team pieces together the contradictory clues, the discovery of the young truck driver’s body and an apparent suicide note leads the investigation toward an even darker truth hidden behind the accident.
