This teenager in china is talking on her cell phone when she's suddenly swallowed by a hidden hole in the sidewalk.
China's c-c-t-v reports the sidewalk had been eroded by underground water, and she fell into an 18-foot pit.
A cab driver who witnessed her plunge jumped into the hole himself.
Firefighters got them both safely back above ground.
Family members used this surveillance video to find the cabbie and offer their thanks.
