You can see in the video how this mom and her child are walking off an elevator in what appears to be an office building. As they wait to access the office, the child wanders off to a nearby balcony.  There is a railing there, but there are openings that would allow a small child to fall through.  Somehow, from several feet away, the mother is able to catch her child in mid-air before what would’ve been a devastating fall.
