The setting for this drone video is a gorgeous, sunny beach day, but it's covering something creepy going on underwater.
The camera tilts up from a swimmer peacefully slicing through the beautiful waters off South Beach, Miami to the happy-looking summertime coast.
Suddenly, it cuts to a shadowy figure swimming underwater, and you can tell that it's not far from shore, or from where the swimmer was bathing so peacefully. Turns out it's a tiger shark in dangerously close-to-shore waters and the drone actually shows it calmly gliding between swimmers mere feet off shore.
It's freaky enough to warrant a watch, and to make you think twice before swimming in warm waters.
