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.

As the most dammed, dibbed, and diverted river in the world struggles to support thirty million people and the peace-keeping agreement known as the Colorado River Pact reaches its limits, WATERSHED introduces hope. Can we meet the needs of a growing population in the face of rising temperatures and lower rainfall in an already arid land? Can we find harmony amongst the competing interests of cities, agriculture, industry, recreation, wildlife, and indigenous communities with rights to the water? Sweeping through seven U.S. and two Mexican states, the Colorado River is a lifeline to expanding populations and booming urban centers that demand water for drinking, sanitation and energy generation. And with 70% of the rivers’ water supporting agriculture, the river already runs dry before it reaches its natural end at the Gulf of California. Unless action is taken, the river will continue its retreat – a potentially catastrophic scenario for the millions who depend on it.
