When Chuck Bartowski 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. With the government's most precious secrets in Chuck's head, Major John Casey of the National Security Agency assumes the responsibility of protecting him. His partner is the CIA's top agent -- and Chuck's first date in years -- Sarah Walker. They'll try to keep him safe by trading in his pocket protector for a bulletproof vest. Also starring are Joshua Gomez as Morgan Grimes, Chuck's best buddy, and Sarah Lancaster as Chuck's ever-supportive sister, Ellie.
