In the spring of 1927, after weeks of incessant rains, the Mississippi River went on a rampage from Cairo, Illinois to New Orleans, inundating hundreds of towns, killing as many as a thousand people and leaving a million homeless.

The "bomb cyclone" that swept across the Great Plains in March 2019 became, in its cost and scope, the worst natural disaster in Nebraska's history. As the storm began, up to 45 inches of snow swept across Colorado and Wyoming into Nebraska and Iowa. Then, warm air turned the blizzard into a deluge. With the ground still frozen hard and unable to absorb the rain, water overflowed into creeks, rivers and ponds already iced over or at capacity, causing record water levels. The people of Nebraska stood in the center of the bullseye. As the unlucky combination of ice, snow and rain caused historic flooding, towns became islands. Cattle, surrounded by water, suffered without food. When the ice broke loose from frozen rivers, it took on a life of its own, moving downstream and swiftly destroying bridges, dams, livestock, homes and businesses. The documentary lays out a one-of-a-kind narrative of this fast-moving tragedy and subsequent efforts to rebuild lives and communities, using news footage and video, photos and recollections from rural Nebraskans who experienced the extreme weather. And The Floods Came at 10:00 pm.
