On a quiet October night in 1973, two friends were fishing in Pascagoula, Mississippi. Their lives changed forever when a strange craft appeared.

Charles Hickson and Calvin Parker's terrifying experience became one of the most compelling UFO cases in history. What happened during those missing 20 minutes? Why did these men insist they were telling the truth for decades?

But there's more to this story than just one night. There are many similar encounters and many possible explanations, both natural and supernatural. 

Whether the story is true or not, one thing is for sure: It was a nightmare.
