12-year-old Cornelius Fillmore (voiced by Orlando Brown), a juvenile delinquent with a record, was caught raiding the school's new chalk shipment. He was "arrested" and given a choice by the safety patrol officer who caught him, either help him solve another case or spend the rest of middle school in detention. Fillmore decided to help out and he eventually decided to join up with the safety patrol. The show is based around him and his partner Ingrid Third (voiced by Tara Strong) at X Middle School, which is located in the suburbs of Minneapolis and Saint Paul in Minnesota. The show's format parodies that of hard-boiled police dramas.[3] X's safety patrol is much more actively involved in student behavior than a typical school's safety patrol, and officers often seem to spend more time patrolling than normally attending class, although they can be seen attending at times. As part of the Safety Patrol at X Middle School, Fillmore and Ingrid solve crimes and mysteries. The series usually presents kid-friendly versions of common crimes, such as stolen scooters, smuggling tartar sauce, holding illegal frog races, and counterfeiting collector cards.
