You're likely thinking of the Disney movie "The Lion King," where the climax occurs when Simba confronts Scar. However, "When Moon Shines Its Magic Over Monument Valley" is a song from the film.

Since the song is not a narrative, there isn't a defined climax. It's a beautiful ballad highlighting the mystical beauty of Monument Valley under the moonlight.

Could you clarify your question? Are you looking for the climax of the movie itself, or perhaps something else related to the song?
