In Chuck, the world's nerdiest secret agent is back in the one-hour action-comedy series. Chuck Bartowski (Levi, Less Than Perfect) continues as the computer geek, working at a Buy More electronics store, who unwittingly becomes the government's most vital secret agent. Chuck is transformed into the Intersect 2.0 after another data download into his brain. This time, he not only knows government secrets, but he is also well equipped with deadly fight skills. Chuck has the potential to become a real agent, but he has one problem -- his emotions. Now he faces the battle of keeping his emotions in check in order to protect himself and the people around him.

The ever stoic Colonel John Casey (Adam Baldwin, My Bodyguard) returns with partner Sarah Walker (Yvonne Strahovski, Gone), one of the CIA's top agents and Chuck's dream girl. As Chuck assumes his new role as the Intersect 2.0, Casey and Sarah need to protect him but also help him become the agent he is destined to be.

Also starring are: Joshua Gomez (Without a Trace) as Morgan Grimes -- Chuck's best buddy; Sarah Lancaster (What About Brian) as Chuck's ever-supportive sister Ellie; Ryan McPartlin (Living with Fran) as Devon Woodcomb (also known as "Captain Awesome"), Ellie's husband. Chuck's Buy More team consists of Big Mike (Mark Christopher Lawrence, The Pursuit of Happyness) and the Nerd Herd, which includes Lester (Vik Sahay, Time Bomb) and Jeff (Scott Krinsky, The O.C.)
