Chuck - Episode Guide

Chuck Bartowski is a computer geek that gets 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. 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, Sarah Walker.

As Chuck Bartowski continues to come to grips with his newly adopted life as a spy, tension builds between his recently appointed partners Sarah Walker and John Casey. When a doctor who seems to have a solution to Chuck's problem is killed, Casey and Walker turn the blame at one another. Both agents persistently try to convince Chuck that the other one is responsible and now it is up to Chuck to decide which one to trust. Who will he choose?

Chuck Bartowski is finding out that living two separate lives is not going to come easy. After being challenged by his boss at Buy More, Chuck needs the help of his best friend Morgan and the Nerd Herd, to prove that he is up to the task and ready to become assistant manager. Meanwhile, Sarah and John force Chuck to go undercover for his first real spy mission. It seems that Chuck's two different lives are learning to Tango, but which one will learn to take the lead?

Chuck faces an unusual task, when Sarah's hot colleague from the CIA shows up requesting help for a mission. Morgan tries to get Chuck to set him up with Sarah's new friend.

Chuck faces his first moral dilemma as a spy. When agents Sarah and Casey refuse to help an unauthorized mission that is taking place in Chinatown by a top Chinese spy, Chuck is faced with a tough decision. Either go against the U.S. government and his friends, or do what he believes is right? Meanwhile, Morgan is caught in a dilemma of his own when Buy More forces him into a sales competition that could cost him his job.

Chuck accidentally runs into a fellow government agent who seems to be living a similar life. It turns out this agent is a gadget whiz, whose brain makes him a national security asset and a dangerous liability, much like Chuck.

Meanwhile, Morgan starts developing a new relationship with an unlikely girl.
