Weaving together dozens of professional and amateur archival sources, along with dramatic interviews with the people behind the cameras, Witness: Joplin Tornado reconstructs the deadliest tornado in modern times, through the eyes of those who lived through it. A group of strangers huddle together in a convenience store cooler, shrieking in terror as the tornado tears apart everything around them. A husband-and-wife stormchasing team find themselves caught in the teeth of the storm, then pressed into service when it finally passes. A young mother sobs as she surveys her daughter’s destroyed bedroom. Yet all the while they film, using their cameras to record both the harrowing experience of the storm itself and the shock of what confronted them after — homes destroyed, neighborhoods flattened, a city devastated. Witness: Joplin Tornado tells the story of that day and its aftermath entirely through the videos and voices of the survivors.
