The officers are working to move drag racing off the streets onto a regulated drag strip. Working with various racing organizations they finally meet the requirements for insurance, etc. provided by the drag strip owner. He also requires that the drivers keep the noise down in the streets surrounding the strip. However, the day before they are to start racing the timing and audio equipment at the drag strip are stolen. When he announces he has replacement equipment on the way, the street organizer of the races who stands to lose money puts on a race in front of the drag strip owner's own home. Malloy, however, finds evidence that indicates the street organizer stole the equipment trying to stop the legal racing.
