Firefighters Escape Burning Home's Fall

The video is so intense, it could be from the set of a Hollywood action movie. Watch above video as firefighters battled a three-alarm fire that consumed a 2-story home in Boise, Idaho.

Captain Randy Christensen noticed the wall of the house starting to bow, and quickly warned fire crews to get out of the way. Just fifteen seconds after his warning, the home gave way, CNN's Michaela Pereira reports.

A few were pelted with burning debris and others were knocked to the ground, but no one was trapped inside, a blessing Boise fire Chief Dennis Doan recognizes: "we could have had firefighters trapped underneath there. it was chaos for a bit, because for a while we did think we had one," he says.

Investigators are still trying to uncover the source of the inferno.
