Chuck

At the end of season two, Chuck was transformed into the Intersect 2.0 after receiving another data download into his brain. This time, he not only knows government secrets, but he is equipped with the knowledge and coordination of deadly fight skills. Now that Chuck has proven himself to be an asset, and knows Kung-Fu, he finally has the potential to become a real agent. There's just one problem — his emotions. Chuck must keep them under control in order to protect himself and the people around him.

Chuck gets a new mission when Sarah's best friend comes through town with her fiancé, Karl (guest star VINNIE JONES - Snatch, X-Men: The Last Stand). But things get complicated when, while on the mission, Chuck wants to hash out his and Sarah's relationship problems. Can he learn to keep his emotions in check? Meanwhile, Morgan finds himself in trouble when he lies to Jeff and Lester.

Though Chuck tries to always protect his family from his spy life, he can't stop Ellie and Awesome from stumbling into an international incident. Chuck must use his relationship with Awesome to protect a visiting dictator, Premier Goya (guest star ARMAND ASSANTE - American Gangster), who is the target of an assassination. While Awesome is excited about the prospect of being a spy, Chuck is more concerned with Awesome and Ellie's safety.

When Awesome is mistaken for a super spy by the evil Sydney Price (guest star ANGIE HARMON - Law & Order), Chuck must become Awesome's handler and show him the spy ropes. While on a mission for The Ring, they meet the mysterious Daniel Shaw (recurring guest star BRANDON ROUTH - Superman Returns). Meanwhile, Morgan gets promoted to assistant manager at the Buy More and must deal with the latest hijinks from Jeff and Lester.

CIA agent Daniel Shaw (recurring guest star BRANDON ROUTH) assigns Chuck to his first solo mission in Paris, ignoring Sarah and Casey's wishes. During the flight to France, Chuck befriends Hannah (recurring guest star KRISTIN KREUK - Smallville) and flashes on another passenger — the imposing Hugo Panzer (guest star STONE COLD STEVE AUSTIN - WWE Smackdown!). Meanwhile, Casey helps Morgan battle Jeff and Lester for control of the Buy More.

Chuck juggles his two lives as he trains new Nerd Herder Hannah (recurring guest star KRISTIN KREUK - Smallville) and gets his very own asset who is caught up with The Ring. Chuck thinks he can handle his asset all on his own but Sarah and Casey feel the need to intercede. Meanwhile, Awesome must lie to Ellie when she starts to ask questions about Chuck. And Morgan, Jeff and Lester do some recon work to learn more about Hannah.

Chuck and Hannah (recurring guest star KRISTIN KREUK) unexpectedly become part of agent Daniel Shaw's (recurring guest star BRANDON ROUTH) latest mission. Much to Sarah's chagrin, she gets paired with Shaw, who seems to be trying to get close to her. Meanwhile, Morgan and Ellie continue their mission to get to the bottom of Chuck's secretive and strange behavior.

Chuck promises to cook dinner for Hannah (recurring guest star KRISTIN KREUK), Ellie and Awesome, but first, for his latest mission, he must assume the identity of the world's most dangerous assassin. Meanwhile, Sarah is determined to keep her relationship with Shaw (recurring guest star BRANDON ROUTH) strictly professional.

Chuck feels like his life is falling apart when he can't flash and gets left behind on a mission. While Shaw (recurring guest star BRANDON ROUTH), Sarah and Casey go on without him, Chuck finds himself in a sticky situation back at the base. DIEDRICH BADER (The Drew Carey Show, Batman: The Brave and the Bold) guest stars.

Casey carries out a side mission for his old commanding officer, Colonel James Keller (guest star Robert Patrick - Terminator 2: Judgment Day, The Unit, The X Files), but it leads to Casey committing treason. When Chuck learns the dark truth about Col. Keller, he and Sarah set out to break Casey out of jail and clear his name. Meanwhile, Awesome's plan to keep Ellie out of danger gets more difficult when she gets her dream fellowship.

Chuck learns that his latest solo mission will be a final test to see if he is ready to be a spy. Chuck needs to put everything he has learned into action to avoid going back to his old life while Sarah and Shaw (recurring guest star BRANDON ROUTH) observe his every move.

Chuck has his pick of the best CIA agents for an undercover operation, but he only has one girl in mind for the job: Sarah. Casey, Morgan and Awesome team up to help Chuck win her back. Recurring guest star BRANDON ROUTH appears as Daniel Shaw.

Chuck, Sarah and Shaw (recurring guest star BRANDON ROUTH) reunite to find the Ring operative behind the death of Shaw's wife. Sarah has faith that Shaw is ready for the mission but Chuck is worried about his emotional stability. Meanwhile, Morgan considers leaving the Buy More.

While in Europe, Sarah and Chuck realize they're traveling on a train with Spanish spies. Even though they're all alone, they decide to take on these rogue agents, but this impromptu mission does not go smoothly. Meanwhile, General Beckman (recurring guest star BONITA FRIEDERICY) orders her newest "unlikely" spy team — John Casey and Morgan Grimes — to track down the missing couple.

Chuck and Sarah are assigned to train under Craig and Laura Turner (guest stars FRED WILLARD -- Anchorman: The Legend of Ron Burgundy, Waiting for Guffman and SWOOSIE KURTZ - Pushing Daisies, Sisters), a married CIA team who, despite their impeccable record, hate one another. The Turners' stormy relationship forces Chuck and Sarah to wonder if they're doomed with the same fate. Meanwhile, Casey must train the newest member of the team — Morgan.

Chuck begins to have disturbing dreams, and believes a recent dream predicts danger for a visiting head of state. General Beckman (recurring guest star BONITA FRIEDERICY), however, is unconvinced and assigns Chuck to meet with CIA psychiatrist Dr. Leo Dreyfus (guest star CHRISTOPHER LLOYD -- Back to the Future, Taxi). Meanwhile, Ellie gets surprising news and Anna (former series star JULIA LING) returns to the Buy More to talk to Morgan.

After his last dream, Chuck asks Morgan to help him on a side mission. Their investigation becomes complicated when Chuck's dad, Stephen J. Bartowski (recurring guest star SCOTT BAKULA -- Men of a Certain Age, Quantum Leap, Enterprise), returns and learns that Chuck downloaded the Intersect 2.0. Luckily, Chuck's father may be able to help his son.

The Ring is closing in on Chuck and Operation Bartowski. Fortunately, Chuck's dad, Stephen (recurring guest star SCOTT BAKULA), is working hard to save his son. Meanwhile, Casey must secretly protect his daughter from the Ring, and Big Mike receives some serious news about the Buy More.
