First episode with new "action" opening titles. The other police dramas Crawford Productions was producing at the time, Division 4 (1969) and Matlock Police (1971), underwent similar alterations to their titles at around the same time. The new sequence sees the Holden replaced with a Chrysler Valiant.
Chrysler would be the last of four manufacturers, after Studebaker, Ford and Holden, to have their cars featured in the series.
