Episode Title: Shut Up, Dr. Phil (from prompt).
Series: Supernatural.
Characters: Sam Winchester, Dean Winchester, Maggie Stark, Donald.
Plot: Sam and Dean encounter Maggie Stark, a witch. She has caused numerous deaths in a small town. They find her husband, Donald. Donald explains Maggie is angry because of his affair and is targeting townspeople.
The synopsis is very short.
The sources provide context about the series (creator, cast, general premise, broadcast history).
The prompt asks for a 280-380 word recap.
Problem: The provided synopsis only contains about 50 words of plot information. If I strictly follow "Use only supplied facts" and "If the synopsis is sparse, stay concise rather than guessing," I cannot reach 280 words without repeating myself or adding fluff, which violates the "neutral, encyclopedic prose" and "never invent" rules.
