Malloy and Reed are chosen to ride in Air-70 to observe how the LAPD's air patrol works. The chopper's cases include searching for two robbery suspects inside a high-rise building and tracking an escaping murder suspect.

Malloy and Reed take to separate helicopter units to continue their observations. The choppers assist in a stolen light plane from LAX by a distraught man, track two robbery suspects fleeing in separate cars, and assist in a nighttime house fire.

Malloy and Reed investigate the death of an old man wearing an unusual belt, which leads to the case being turned over to Frauds Division, who finds that Dr. Gantman, running a clinic, is treating a blind seven-year-old patient with a pituitary gland condition but his "treatment" is worthless and preventing a real treatment (removal of the gland). Later, a TV repairman who makes oscillator belts for Gantman is busted for bookmaking and agrees to testify against the doctor, but Gantman demonstrates his "treatment" in open court and fails miserably.

Note: This episode, in which Reed and Malloy appear only briefly, was intended to be the pilot for a new Mark VII series focusing on the Los Angeles District Attorney's Office, and was directed by Webb himself. However, no such series came to be.
