Chuck is an action-comedy/spy-drama television program created by Josh Schwartz and Chris Fedak. The series is about an "average computer-whiz-next-door" who receives an encoded e-mail from an old college friend now working in the CIA; the message embeds the only remaining copy of the world's greatest spy secrets into Chuck's brain.
