This is a theme that plays in some more dangerous scenes. There are a couple of these, and depending on the emotional content of whatever catastrophe the characters are going through, a different one will play.

For this particular theme, the feel is supposed to be more akin to a slow burn (read: not necessarily requiring involvement from massive explosions.) Something bad happened, and you need to get out of Dodge as quickly and quietly as possible. The theme probably is mostly going to relate to the more political parts of the story, like when various factions go after one another.
