The Rockford Files - Season 6 Episode 12 Deadlock in Parma

In the series finale, Jim Rockford drives off into a California sunset in his wounded Firebird, after being ensnared in a small-town council battle with big implications. While trout fishing in the mountains, the vacationing PI becomes the emergency proxy for a fellow angler, an environmentalist councilman, felled by appendicitis. But the seemingly-innocuous proposition for a Parma city park, attracts a trailer load of New Jersey mobsters who urge Rockford to keep his vote green, or sleep with the fishes. Meanwhile, this town council in the land of endless propositions, acts to force their temporary member Rockford to go fishing under the moonlight, but not in Parma.
