20 Years Later, New Documentary Looks at Deadliest Tsunami in History

It was one of the deadliest natural disasters in modern times. Some 20 years ago a massive tsunami in southern Asia, triggered by a 9.1 earthquake off the coast of Indonesia, killed more than 200,000 people in 14 countries. A new documentary, "Tsunami: Race Against Time,” looks back at that devastating day -- December 20, 2004 -- with never-before-seen footage.
