Four panelists took turns questioning the person with the secret to determine exactly what the secret was. A nominal financial award was given to a contestant whose secret (flashed on the TV screen for the viewing audience) could not be guessed by the panel. Each show gave three regular contestants an opportunity to stump the panel, and also had one celebrity guest with his own secret to hide.Gary Moore was the first mc of the programs during it's early run on CBS TV..on the later Syndicated version and on a cable tv version..the series was hosted by Steve Allen.
