In the initial concept, Sabrina Duncan, Jill Munroe, and Kelly Garrett have graduated from the police academy in Los Angeles, California. Despite proving their capability during training, all three have subsequently been assigned to be a meter maid, office worker, and crossing guard, respectively. Dissatisfied with these jobs, they are recruited to work for the Charles Townsend Agency as private investigators. All of this is explained in the opening credit sequence; neither the pilot film nor subsequent series ever actually depicted an "origin story" as they are seen to have been working as investigators for some time as of the start of the pilot.
