Chuck

When Chuck Bartowski (series star ZACHARY LEVI) 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 with his best buddy, Morgan Grimes (series star JOSHUA GOMEZ), and who lives with his ever-supportive sister, Ellie (series star SARAH LANCASTER).

As Chuck continues to come to grips with his new life as a spy, tension builds between his recently appointed partners, Sarah and Casey. When a doctor who seems to have a solution to Chuck's problem is killed, Casey and Sarah blame each other. Both agents persistently try to convince Chuck that the other one is responsible. Now it's up to Chuck to decide whom to trust.

Chuck is finding out that living two separate lives is not going to be easy. After his boss at Buy More challenges him, Chuck enlists the help of Morgan and the Nerd Herd to prove himself worthy of becoming assistant manager. Meanwhile, Sarah and Casey force Chuck to go undercover for his first real spy mission.

Chuck takes on an unusual task when Sarah's hot colleague from the CIA requests help with a mission. He finds out that a million-dollar diamond hidden in a Malibu mansion is being used to help fund terrorists and must help these two beautiful women steal it back. Meanwhile, Chuck begins to realize that Sarah's double life, which she is very good at maintaining, really makes it hard for him to get to know who she really is. And Morgan tries to get Chuck to set him up with Sarah's friend.

Chuck faces his first moral dilemma as a spy.
