NBC just released a website where viewers can learn more about the titular hero of the new fall show "Chuck." The site is ChucksSecret.com, and it puts users in the role of a secret agent who has hacked into Chuck Bartowski's laptop. Why are the CIA and NSA interested in a 20-something tech support nerd? Check out the site for some clues.

From executive producer Josh Schwartz ("The O.C.") and executive producer-director McG ("Charlie's Angels," "We Are Marshall") comes a one-hour comedy action series about Chuck Bartowski (Zachary Levi, "Less than Perfect,") - a computer geek who is catapulted into a new career as the government's most vital secret agent.

When Chuck opens an e-mail subliminally encoded with government secrets, he unwittingly downloads an entire server of sensitive data into his brain. Now, the fate of the world lies in the unlikely hands of a guy who works at a Buy More Electronics store. Instead of fighting computer viruses, he must now confront assassins and international terrorists."

http://ChucksSecret.com is brand new, and some of the stuff is still "coming soon," but it will be rolling out in the coming weeks.

"Chuck" premieres Monday, Sept. 24, 8-9 p.m. on NBC.
