Kokku Hoshimitsu of the First Investigative Division is a professional “cook inspector” who solves cases. His investigation policy is “food doesn’t lie”. He has no tolerance for murderers who eat their favorite food without a care after getting away with a crime. In order to understand the victims, he will recreate what they ate and focus on reaching a deduction. His partner is the rookie Nanase Azumi who fulfilled her long-cherished dream to be a detective after developing a love of detective dramas. However, she finds herself stressed to the max because of his unrestricted investigations and also sandwiched between the high-handed detective Nekota Norio.
