What scenario might be described in the sentence, "She went quiet as soon as she saw the footage"?

An example might be if a woman suspected her husband was having an affair so she hired a private detective to follow & film him.

The detective gave her his report which included video of her husband and she went quiet as soon as she saw the footage.

The scenario of a woman promptly going quite upon watching a video or film.

It's notable that it says "saw" instead of "had seen."  "Had seen" would clearly indicate that she "went quiet" after the footage had finished playing.  "Saw" means she "went" quiet at the start.  That's significant because someone going quiet after seeing something can be inferred as meaning something different than someone going quiet at the start, a different scenario.  However, lots of people have bad grammar, and it wouldn't be unusual for someone to incorrectly say "saw" in place of "had seen."  So if it matters when exactly the going quiet began in determining the scenario, it would be wise for there to be a follow-up question to button that down.
