Excerpt
Excerpt From http://www.truecrypt.org/docs/hidden-volume.php :
It may happen that you are forced by somebody to reveal the password to an encrypted volume. There are many situations where you cannot refuse to reveal the password (for example, due to extortion). Using a so-called hidden volume allows you to solve such situations without revealing the password to your volume.
....
The password for the hidden volume must be different from the password for the outer volume. To the outer volume, (before creating the hidden volume within it) you should copy some sensitive-looking files that you actually do NOT want to hide. These files will be there for anyone who would force you to hand over the password. You will reveal only the password for the outer volume, not for the hidden one. Files that really are sensitive will be stored on the hidden volume.
A hidden volume can be mounted the same way as a standard TrueCrypt volume: Click Select File or Select Device to select the outer/host volume (important: make sure the volume is not mounted). Then click Mount, and enter the password for the hidden volume. Whether the hidden or the outer volume will be mounted is determined by the entered password (i.e., when you enter the password for the outer volume, then the outer volume will be mounted; when you enter the password for the hidden volume, the hidden volume will be mounted).

TrueCrypt's hidden volume feature provides implementation for two-password access, where access to more sensitive information is granted only with the "primary" password (while a secondary password allows access to less priviledged or unimportant data).
