Steve Franken, best known to baby-boomers as the snotty Chatsworth Osborne Jr. on the old Dobie Gillis TV series, is here cast in a straight role as "The Ferret", a pro-environmental terrorist. Targetting manufacturers whom he regards as shameless polluters, the Ferret specializes in giving these "offenders" a taste of their own medicine, usually in a messy or violent fashion. It is up to Officers Reed (Kent McCord) and Malloy (Martin Milner) to locate and stop the Ferret before he ends up killing somebody.
