A car carrying three teenage girls plunged into a river in Mississippi.
Within moments, the car was sinking with all three girls trapped in the water and screaming for help.
Sixteen-year-old Corion Evans saw what was happening, kicked off his shoes and jumped in.
He reached the girls and began getting them back to shore one at a time, swimming one girl to safety before turning around and going back into the river for the next.
After the third girl was safe, it looked like the rescue was finally over. Then Corion heard someone else calling for help.
A police officer who had entered the water to assist was now struggling himself and beginning to drown.
So after already rescuing three people, Corion turned around and swam back out again. He reached the officer and helped bring him safely back to shore too.
By the time Corion finally came out of the water, this 16-year-old had helped save four lives in a single day.
Now THAT is the kind of young hero I want to hear about.
