The synopsis is extremely brief: "The team tries to track down a serial killer, while Abby heads south of the border to give a speech with McGee in tow."
The word count requirement is 280-380 words.
Problem: The provided information is insufficient to reach 280 words without violating the "Never invent or guess... plot points" and "If the synopsis is sparse, stay concise rather than guessing" rules.
Constraint Conflict: I am instructed to write 280-380 words, but I am also instructed not to invent facts and to stay concise if the synopsis is sparse.
Resolution: In professional archiving/instructional logic, the "do not invent" and "only use provided facts" rules are absolute. If I cannot reach the word count without inventing facts, I must prioritize the factual integrity. However, I can expand on the context of the series provided in the sources to add substance without inventing plot details.
