Overview Requirement: 160-220 words.
Problem: The provided sources contain almost zero information about the specific narrative arc of Season 5. They only give the air dates (Sept 29, 1986 to April 13, 1987).
Constraint Check: "If a detail is not in the provided material, you omit it rather than guess." "You never invent or guess... plot points."
Conflict: I cannot write a 160-220 word summary of the narrative arc if the sources don't provide one. The sources only mention the general premise of the series (Dick and Joanna owning the Stratford Inn, Dick's career, staff members).
Strategy: I must describe the setting and characters as established in the sources, but since the prompt asks for a summary of this season's narrative arc, and the sources provide no season-specific plot, I am stuck. However
