"Chuck" is an action-comedy-drama created by Josh Schwartz (The OC, Gossip Girl) and Chris Fedak. At the start of season one, Chuck (Zachary Levi), a typically geeky computer nerd living in Burbank, California, receives an encoded e-mail from an old college friend working in the CIA. The message embeds a neural supercomputer called the Intersect into his brain. Both the National Security Agency (NSA) and the CIA want the secret government information in Chuck's head returned, so they dispatch agents Col John Casey (Adam Baldwin) and Agent Sarah Walker (Yvonne Strahovski) to retrieve the data. Chuck experiences flashes of information from the database in his head activated by certain triggers such as faces, voices and various objects. In order to preserve Chuck's safety, Walker poses as his girlfriend and Casey works undercover at Chuck's place of employment, an electrical store called the Buy More. A lot of the comedy is derived from the characters who work alongside Chuck, including Morgan (Joshua Gomez), Lester (Vik Sahay) and Jeff (Scott Krinksy). Away from the Buy More, Chuck's sister Ellie (Sarah Lancaster) and her partner Devon (Ryan McPartlin) are always encouraging him to make progress in his professional and romantic life. As the seasons progressed, Chuck developed the skills of a spy and the twist at the end of season two saw him learning kung fu from the Intersect.
