It is a financial scandal that shocked the world.  One year later, its secrets are still being revealed. Authorities say flamboyant Texas billionaire Sir Allen Stanford bilked investors out of billions of dollars in order to fund his lavish lifestyle.

The alleged scheme collapsed on February 17, 2009 when federal authorities raided Stanford's office, claiming billions of dollars in customer funds were missing.  Soon after, Allen Stanford gave his only in-depth television interview to CNBC Senior Correspondent Scott Cohn in the original documentary "Secrets of the Knight: Sir Allen Stanford and the Missing Billions."  Now, CNBC follows up with "More Secrets of the Knight” and uncovers more in the story that stretches around the world.

In an exclusive interview, you’ll hear from Stanford’s attorney Kent Schaffer, who tells how he plans to prove his client, is innocent.   We’ll investigate allegations that Stanford bought influence with members of Congress and interview investors, many of whom lost everything.   And, where were the regulators? "More Secrets of the Knight" examines why it took authorities years after the initial complaints to move in.
