Right off the bat, the trailer shows what's up: Amber's been snatched, and they're busting their butts to get her back. Her family, especially her brother and hubby, are right in the thick of it. You can tell they're ready to do anything, but they've got serious hurdles, like political games and massive problems getting things done.
It also hints at all the political stuff going on behind the scenes. There's talk of the CIA being involved, the possibility of a war, and even a quote from an Al Qaeda leader that throws a global spin on things. He basically says "democracy is toast," which really ups the ante.
The trailer really emphasizes how dangerous the rescue mission is. These folks are up against tough odds, like resistance, warnings from the military ("No raid allowed!"), and threats of payback. The possibility of someone dying is ever present, even though the family is holding onto hope she gets home safe.
