Most of the program's storylines involved Isis coming to the rescue of high school students who found themselves in danger due to unwise choices. A notable exception was the two-part series finale, "Now You See It...", and, "...Now You Don't", which had an espionage-related plotline revealing that Rick Mason has been working secretly for the U.S. government on a weather-making machine. This two-parter introduced a trio of crime-fighting teens dubbed "The Super-Sleuths;" the double episode was intended as a backdoor pilot for a "Super-Sleuths" series, which never materialized.
