Incredible acts of heroism were caught on tape in 2017. In one heart-stopping incident, a kayaker flips into the water. His kayak was swept away as raging waters surged around him. The man desperately gasps for breath when he suddenly disappears under the water. That's when a good Samaritan made a heroic move to save him. Incredibly, 64-year-old Daniel Hartung only suffered a broken rib and some bruising.
