Secrets of the Unknown daringly showcases the bizarre, the terrifying, and the unmistakably real. First, explore the scientific cause behind the unnatural disasters of twisters with testimony from survivors and "storm chasers." Then, speak with people who believe they've spotted UFOs - as well as those who claim to have been abducted by aliens and subjected to painful tests, before being safely returned to their homes.
