Matthew McConaughey's search for people he could help led him to Waveland, Mississippi, a community devastated by Hurricane Katrina. He is first struck by how quiet everything is. "To look around," he says, "and see how much earth, trees, houses, structures were moved—left, right, up and down—and for all of it to have settled…that's very eerie."

In Waveland, Matthew meets an engineer who built his "hurricane-proof" dream house to withstand 160 mph winds—but despite his best efforts and the strength of steel and concrete, the builder's house is now gone. "It hurts," he says, "but you can't do anything about it. Mother nature, you know…."
