On April 19, 1995, the deadliest act of domestic terrorism in U.S. history devastated the nation, claiming 168 lives—including 19 children—and injuring hundreds more. The bombing of the Alfred P. Murrah Federal Building shattered families and changed America forever.

Now, 30 years later, National Geographic has unveiled the trailer and key art for its new three-part docuseries, Oklahoma City Bombing: One Day in America, a raw and unflinching account of that tragic day, told by those who lived through it. The series premieres April 2 at 8/7c on National Geographic and streams the next day on Disney+ and Hulu.
