Arguably the most dysfunctional culture of the past few centuries, North Korea is a cosmically mad movie waiting to happen.

In the meantime, FRONTLINE will go inside the Secret State of North Korea tonight.

Using undercover footage smuggled out of the country, tonight's must-watch documentary delivers a rare and revelatory look at the realities of life in a country where:

• Just being caught with illegal DVDs could mean immediate imprisonment, or even execution.
• Until recently, it was illegal for women to wear pants instead of skirts or dresses.
• As many as one in 100 citizens is a political prisoner.

Secret State of North Korea premieres tonight at 10 p.m. on KCTS Channel 9.
