In April of 2011 the United States experienced a month of extraordinary violent tornado’s, it was the deadliest recorded in modern times. Stretching from Oklahoma to North Carolina over 600 tornados were witnessed and the result of these caused a tremendous amount of damage and loss of life.

Over the course of two days (April 26 – 27) there were more than a hundred separate twisters, these twisters cut a devastating path of destruction through the south and took the lives of many. This two day period was coined the “super outbreak”.

With a combined use of professional and amateur footage this National Geographic film tells the story of this freak event as witnessed by those who lived through it.
