Use ONLY verifiable facts from the provided SYNOPSIS and SOURCES.
No invented titles, names, dates, episode counts, awards, ratings, box-office, viewership, or plot points.
If a detail is not in the material, omit it.

SYNOPSIS: "NCIS is called in to investigate when a Lieutenant returns home on the eve of Halloween to find a surprise party being thrown for someone else at his place."
SOURCES:
