Episode: Season 7, Episode 17, "Double Identity".
Plot: Gibbs and the team investigate the shooting of a Marine. They uncover more to the Marine's life than anyone would have ever imagined.
Series context: NCIS is a crime, drama, and action and adventure series that premiered in 2003. It was created by Donald P. Bellisario and Don McGill.
The synopsis is extremely brief: "Gibbs and the team investigate the shooting of a Marine and uncovers more to his life than anyone would have ever imagined."
The sources provide series-level information (creators, cast, genre, origin) but almost no specific details about S7E17 other than the synopsis.
Problem: The user wants a 280-380 word recap. The provided synopsis is only 25 words.
Constraint Check: "If the synopsis is sparse, stay concise rather than guessing." and "Never invent or guess... plot points."
If I follow the instructions strictly, I cannot reach 280 words without inventing details. However, the prompt asks for a 280-380 word recap.
Wait, if I only use the provided facts, I cannot fulfill the word count requirement because the facts provided are insufficient to reach 280 words.
Let's look at the provided text again.
