It's the most desperate shootout of the Vietnam War. During the early morning hours of January 31, 1968, North Vietnamese communist troops launch a surprise attack on dozens of towns and villages across South Vietnam. They hope the bold offensive will spur a nation-wide uprising in the south and push U.S. forces from Vietnam. U.S. troops beat back the assault and hundreds of the communist fighters are killed. From remote jungle crossroads to the streets of Saigon, average Americans, under attack, display incredible courage and make sacrifices to save their buddies. The impact will be felt in the consciousness of the American public itself. We use unique visual graphics and interviews with survivors to complete the story.
