A young Mark Harmon appears as Gus Corbin, a rookie cop with whom veteran mobile officer Jim Reed (Kent McCord) is temporarily teamed. It is Reed's responsibility to show Gus the ropes and teach him to look after himself on the job.

This episode was written by prolific character actor Leo Gordon, whose actress wife Lynn Cartwright is seen in the role of Jan. ~ Hal Erickson, Rovi
