When the choices you make mean the difference between life and death, what would you do? Grab the wheel of a big rig as the truck slides out of control on deadly black ice. Avoid the crushing bite of a killer when you come face to face with a 250-pound American alligator. And dodge the pileup at the bottom when an escalator's brakes fail and it speeds out of control. Are you prepared to save yourself when it's time to Do or Die?
