In May 1953, the Atomic Energy Commission conducted a "safe" nuclear tests shot called "Dirty Harry" near St. George, Utah.
within a few days, more than 4,000 sheep were dead of a mysterious illness. Within a few years, a plague of cancer and birth defects had ripped through the area - a plague that may have caused the cancer-related deaths of John Wayne and over 100 other cast and crew of The Conqueror, which was filmed only miles from the test site. And when the survivors claimed compensation, the government successfully denied all responsibility.

This uncompromising expose of "the greatest government cover-up of all time" brings to light a shocking thirty-year conspiracy of falsified reports, suborned witnesses, and "lost evidence" - a record of shame that, like the testing itself, continues to this day.
