Chuck: The Complete Series

When computer geek 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 and is catapulted into a new career as the government's most vital secret agent. 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). Instead of fighting computer viruses, Chuck must now confront assassins and international terrorists. With the government's most precious secrets in Chuck's head, Major John Casey (series star Adam Baldwin) 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 (series star Yvonne Strahovski).

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. When agents Sarah and Casey refuse to aid an unauthorized mission by a top Chinese spy taking place in Chinatown, Chuck faces the tough decision to 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.

When Chuck meets a fellow government agent with a double life, a gadget whiz whose brain makes him a national security asset and a dangerous liability -- much like Chuck -- he must decide whether to turn the agent in to Sarah and Casey or help him escape. Meanwhile, Halloween, a holiday that means a lot to buddies Chuck and Morgan, is a little different this year, as Morgan feels that Chuck is neglecting their childhood memories and friendship.

When Chuck finds out that his former professor is a government operative who is being hunted because of a sensitive top-secret file, he returns to Stanford University, the institution from which he was expelled. While using his past experiences to determine what the professor knows, Chuck discovers some shocking secrets about his own life. More importantly, Chuck learns the truth about his former friend Bryce Larkin (recurring guest star Matthew Bomer), who was responsible for Chuck's expulsion. Meanwhile, Morgan has problems with the new assistant manager at Buy More.

Chuck battles with his real love life and "cover" love life when he meets a very pretty girl named Lou (recurring guest star Rachel Bilson), who seems interested in the real Chuck. On the other hand, Chuck's relationship with Sarah heats up as they go on a double date with Ellie and Captain Awesome (recurring guest star Ryan McPartlin) and try to explain their sex life. Meanwhile, a poison specialist trying to obtain codes to nuclear facilities uses a "truth" potion to help him get answers. After all are exposed to the serum, Chuck discovers a lot about his partners.

When Chuck starts dating Lou (recurring guest star Rachel Bilson), a sandwich maker, and things seem to be going really well, the situation incites some jealousy from Chuck's "ex-girlfriend" Sarah, who discovers that her feelings may not have been just part a cover story. Things get even more complicated when it is discovered that Lou is in a smuggling ring. Is her relationship with Chuck another fraud, or is it real? Meanwhile, Morgan becomes acquainted with an unlikely girl.

At Thanksgiving, Bryce (recurring guest star Matthew Bomer) returns, after being assumed dead. Secret internal committees trying to destroy the "intersect" -- otherwise known as Chuck's brain -- saved Bryce, hoping that he would help them locate it. But in order to prove to Sarah, Casey and the rest of the CIA that he is not rogue, Bryce needs Chuck's help. Upon seeing former lovers and partners Bryce and Sarah back together, Chuck grows jealous and doubts any future with Sarah. Meanwhile, as Buy More prepares for the biggest shopping day of the year, Morgan is left in charge to ensure that everything goes well.

Still licking his wounds after realizing Sarah still has feelings for Bryce (recurring guest star Matthew Bomer - "Traveler"), Chuck must assume the cover of being Sarah's husband on a mission to foil a politically connected counterfeiter and yachtsman. Emotions and sea legs are tested when Chuck, Sarah and Casey head to the marina to scuttle a plot that also puts an unwitting Morgan and Anna (recurring guest star Julia Ling - "ER," "Studio 60 on the Sunset Strip") squarely in the crosshairs. Meanwhile, it's time for the annual Buy More holiday party -- but the party comes with lots of rules from Big Mike (recurring guest star Mark Christopher Lawrence - "The Pursuit of Happyness").

Chuck discovers that several Russian arms dealers are secretly meeting in Los Angeles. One particular Russian woman catches his attention, and he flashes on her as being Casey's ex-girlfriend. Chuck grows intrigued and begins to pester Casey about his history with the woman. After learning she is set to marry one of the Russian arms dealers, Chuck insists that Casey fights for his woman. Will Casey go after his true love without compromising his identity? Meanwhile, Captain Awesome (recurring guest star Ryan McPartlin) and Ellie reach a tough point in their relationship.

Captain Awesome (recurring guest star Ryan McPartlin) asks Chuck if he can have Ellie's hand in marriage, and then insists that Chuck hold on to the ring until the proposal is planned. Chuck locks the ring in his Buy More locker, but returns the next day to discover everything has been stolen from the store. Meanwhile, Casey and Sarah discover that the CIA has been spying on them in hopes of discovering "the intersect." With Chuck's identity and life on the line, the National Security Agency has no other option than to relocate Chuck into a permanent holding cell. Will Chuck lose his family and friends forever?

In the second season premiere, Academy Award® nominee Michael Clarke Duncan ("The Green Mile") guest stars as Colt, a menacing operative. Chuck prevents Colt from obtaining the Cipher, a device that would ultimately lead to a new Intersect. Chuck is told that this successful mission marks the end of his espionage career and the beginning of a normal life. Free from bullets and bombs, Chuck finally asks Sarah out on a real first date. But Chuck's role as the old Intersect is not good news for everyone, and Casey must deal with a difficult order assigned to him. Meanwhile, at Buy More, Morgan devises an eccentric way to hire a new assistant manager.

Chuck must go undercover to retrieve the Cipher from the sultry but dangerous spy known as the Black Widow (guest star Melinda Clarke - "The O.C."), but in order to get close to his target, Chuck must first learn the art of seduction from the suave and sophisticated Roan Montgomery (guest star John Larroquette - "Boston Legal"), a legendary debonair spy. Unfortunately for Chuck, Sarah and Casey, Roan is no longer the world's greatest spy. Meanwhile, Morgan offers Captain Awesome some advice for a romantic night with Ellie, and Lester struggles to gain respect at Buy More as the new assistant manager.

Chuck is overcome with jealousy when his nemesis -- and Sarah's ex-lover and former partner -- Bryce Larkin (recurring guest star Matthew Bomer) makes an unexpected return. Chuck and Sarah's growing feelings for each other are tested when their latest mission requires Sarah and Bryce to pose as an extremely affectionate couple. Meanwhile, Morgan faces his own challenge at Buy More when he must deal with a gang of bullies from a neighboring sporting goods store in the strip mall called the Mighty Jocks, led by the fearful and intimidating bully, Mitt (guest star Michael Strahan - New York Giants).

Chuck learns more about Sarah's past when they run into her old high school nemesis, Heather Chandler (guest star Nicole Richie - "The Simple Life"). Sarah's teenage insecurities come to the surface and she tries to avoid Heather at all costs. Chuck, on the other hand, does everything he can to hear more about Sarah's hidden life. When Heather's nerdy husband, Mark (guest star Ben Savage - "Boy Meets World"), turns out to be a key player in a new mission, the agents must attend Sarah's high school reunion to prevent the sale of plans for a potentially dangerous super bomber -- but the reunion ends with the ultimate cat fight. Meanwhile, Big Mike leaves town for a day and Lester -- as Buy More's new assistant manager -- decides to implement a new sales policy.

The espionage life is beginning to take its toll on Chuck and everyone is noticing. Chuck tries to explain his unusual behavior to Ellie and to the quirky Buy More efficiency expert Emmett Milbarge (guest star Tony Hale - "Arrested Development," "Stranger than Fiction"), but a new assignment only complicates things. After a global terrorist comes searching for Jeff, Chuck is forced to socialize with Jeff in order to find out what role the oddball plays in the mission. Sarah, Casey and Chuck are all shocked when they discover that the fate of the world and the prevention of World War III rest in Jeff's hands.

While on a Nerd Herd call, Chuck runs into his ex-girlfriend Jill (recurring guest star Jordana Brewster - "The Fast and the Furious") -- the girl who broke his heart. In an attempt to save face, he lies and tells her that he is more successful than he really is. But when Chuck flashes on Jill's boss -- a research scientist who may have developed a deadly bio weapon -- he, Sarah and Casey must find out if Jill is involved. Meanwhile at the Buy More, Big Mike nearly chokes to death, which leads the company efficiency expert, Emmett (recurring guest star Tony Hale), to implement a mandatory CPR course, taught by Captain Awesome.

Chuck and Jill (recurring guest star Jordana Brewster) are enjoying the honeymoon stage of their rekindled relationship. The two lovebirds plan a weekend getaway but have to cancel at the last minute when Casey and Sarah inform Chuck that he is needed for an immediate mission to find corrupt agents in the CIA. Jealousy erupts when Jill finally meets Sarah and learns that Chuck and his handler must pose as a couple. Chuck does his best to reassure Jill that his relationship with Sarah is purely business but only finds himself in more trouble when his mission does not go as planned. Meanwhile, corporate efficiency expert Emmett (recurring guest star Tony Hale) is out to get Chuck and interrogates Morgan to get some dirt on his best friend.

Chuck, Sarah and Casey are shocked to discover that Chuck's girlfriend, Jill (recurring guest star Jordana Brewster), is a Fulcrum agent in search of the Intersect.

Chuck decides to spy on Sarah and sees her on a date with an older man (guest star Gary Cole - "Desperate Housewives," "The West Wing," "Pineapple Express," "Tallagega Nights: The Legend of Ricky Bobby"). Chuck frantically tries to warn Sarah after he has an Intersect flash, but she assures Chuck that she is not in danger and reveals the identity of the mystery man. Meanwhile, Anna wants to move into an apartment with Morgan, forcing him to finally act like an adult. Awesome offers to help Morgan pay for the apartment, but a relic from the past causes Morgan to lose focus on his new grownup responsibilities.

It's the day before Christmas, and everyone is starting to feel the holiday spirit. But when a rogue car chase crashes into the Buy More and everyone is held hostage by the car's driver -- including Awesome and Ellie who have come in to do some last-minute shopping -- true colors begin to show.

Unfortunately for Chuck, neither turns out to be quite what he expected.

After Chuck's father, Steve (recurring guest star Scott Bakula), is kidnapped by Fulcrum, Chuck learns the only chance he has to find him is by putting his trust and life into the hands of the person he trusts the least - his ex-girlfriend Jill (recurring guest star Jordana Brewster). Meanwhile, the Buy More team tries to sabotage Emmett's (recurring guest star Tony Hale) corporate evaluation.
