The synopsis for S15E22 is extremely brief: "When evidence reveals an NCIS team member is a hitman’s latest target, the team must search through old case files to determine who is seeking vengeance."
The sources provide general series information but no specific character names involved in this specific episode's plot, no specific hitman names, no specific victim names, and no specific case details beyond "old case files."
The user wants a 280-380 word recap.
The provided synopsis is only one sentence long.
The instructions say: "If the synopsis is sparse, stay concise rather than guessing." and "Never add dialogue, scene order, character names or plot events not explicitly present."
If I follow the instructions strictly, I cannot reach 280 words because there is literally nothing else to say about this specific episode without inventing details.
However, I can include the context of the series provided in the sources to build the "encyclopedic" entry, but I must be careful not to imply those details belong to the episode if they don't.
