The keyword term "patriots day film plot" functions grammatically as a noun phrase. The main point, or the head of this phrase, is the noun "plot".
In this construction, "plot" is the core subject being identified. The preceding words, "Patriots Day" and "film," act as noun adjuncts (or attributive nouns), which function like adjectives. "Patriots Day" modifies "film" to specify which film is being referenced. Subsequently, the compound modifier "Patriots Day film" specifies the noun "plot." This sequential modification clarifies that the subject is not just any plot, but specifically the plot belonging to the film titled Patriots Day.
Recognizing "plot" as the main noun is crucial because it establishes the article's central theme.
