It's possible you're thinking of the "Stairway to Heaven" storyline that's commonly interpreted as a journey to the afterlife, where a young woman (sometimes depicted as a maiden) is the central figure. However, this story is not directly related to the film or album itself.
The film features the band performing various songs from their repertoire, but it doesn't have a specific narrative structure like "Stairway to Heaven".
If you could provide more context or details about the blond maiden you're referring to, I might be able to give you a more specific answer.
