At a time when the Red Scare was a household term, Americans were keenly aware and alert. It's easy to spot Communism when it's being chanted, when a protest sign hovers in the air, or when those who advocate such a system speak openly about it. Dangerous ideas are not always obvious, however. Communism was cleverly finding new ways to infiltrate American culture with its propaganda.

For this reason, in 1947, Ayn Rand wrote the screen guide printed here for the Motion Picture Alliance for the Preservation of American Ideals.

Whether we like it or not, dangerous ideas always exist, and we must know how to recognize them.
