SYNOPSIS: "Gibbs and the NCIS team partner with a Coast Guard Investigative Service (CGIS) Agent to solve the murder of a Marine gunned down on a dinner boat."
SOURCES:
[1] TMDB: Series overview (murder, espionage, terrorism, stolen submarines).

The synopsis is extremely brief: Gibbs and the team partner with a CGIS Agent to solve the murder of a Marine gunned down on a dinner boat.
The sources provide general series information (creators, cast, origin) but almost zero specific plot details for Season 8, Episode 11.
Problem: The user wants a 280-380 word recap. The provided synopsis is only one sentence long.
Constraint Check: "If the synopsis is sparse, stay concise rather than guessing." and "You write ONLY verifiable facts that are explicitly supported by the provided SYNOPSIS and SOURCES."
Conflict: I cannot reach 280 words without inventing details, which is strictly forbidden. I must follow the instruction to "stay concise rather than guessing" and "omit [details not in the material] rather than guess."
