Chuck Episode 4.23 Chuck Versus the Last Details

The show opens on a glowing canister of thorium in a lab. Mary Bartowski drops down, suspended from above and reaches a black-gloved hand around the canister. Mary hastily retreats as Vivian Volkoff enters the lab with Riley and a scientist. The scientist assures Vivian that The Norseman weapon has finally been reassembled and hands it to Vivian. She passes it to Riley, who activates it, killing the scientist in a test run. When Volkoff and Riley leave, Mary descends again. But armed guards immediately burst in, followed by Riley and Vivian. Riley introduces Mary to Vivian as "the woman who betrayed your father for 20 years." He nods at an armed guard, who knocks Mary unconscious.

Sarah wakes up Chuck and reminds him that they have the day off and today is all about their wedding. Chuck assures Sarah that Ellie, Devon and Morgan are taking over every chore since Sarah's bridesmaids are still away staging a coup. Chuck comments that he has one little thing left to do that Sarah doesn't get to know about. Sarah says that everything is perfect and nothing can go wrong. Chuck scolds Sarah for saying nothing could go wrong - just as there's a clang and a scream from the courtyard. They rush out to see what happened.

They find Morgan dangling dangerously from the balcony, entwined in twinkling lights. Ellie and Devon are panicked, but Chuck tells them all he'll handle it. Chuck flashes, then bounds up the balcony and delivers Morgan to safety. Chuck does a back flip off the balcony. Ellie and Devon are impressed. Ellie snaps back into wedding mode and sends Chuck and Sarah back inside to do "something romantic."

Casey and Alex finish breakfast. As Casey puts the dishes away, Morgan comes in and kisses Alex, telling her how excited he is that she's his "hot date" to Chuck's wedding. Casey shakes his head in disgust but is immediately distracted by an urgent text message. Chuck's mom has been captured by Volkoff and the team must mobilize to rescue her.

At Castle, Chuck and Sarah discuss why Mary would've been working on Volkoff when it was their case. Chuck hasn't talked to her lately, even to ask her about his father and Agent X. Sarah shows Mary's last communique to Chuck. He flashes on a photo of a quarry in a jungle. It's a mine in Colombia with a lot of "bad guy" traffic. Sarah declares that it's a quick flight and they'll have Mary back by the rehearsal dinner. Chuck announces that he needs his best man.

Chuck finds Morgan at the Buy More and explains the situation. Morgan's ready to go on a mission to save Chuck's mom, but Chuck has a different mission in mind. He needs Morgan to save the day in a different way, by creating a romantic montage of Chuck and Sarah for their rehearsal dinner. Morgan remarks that's less "Superman" than he'd like, but he'll do anything Chuck needs. Chuck warns him that Sarah doesn't have many old pictures, so Morgan will have to Photoshop some pictures, maybe of different places she's lived. Morgan assures Chuck that he's on it. They hug as we see Jeffrey filming them from a distance with a handheld camera. Lester comments that their time has come.

Big Mike, Lester and Jeff approach Morgan, asking if Morgan needs footage of Sarah. Lester reveals that they have 1,250 hours of Sarah-related footage. Big Mike explains that his "clients" have spent the last four years developing their filmmaking talent. Morgan asks for the footage. Lester declares that he is a "montage artist," and he'll need first and final cut. Morgan says he can have first cut and then hand it over to Morgan, so he can make it good. Big Mike agrees and shakes Morgan's hand on the deal.

Morgan finds Casey at Castle and reports that his best man chore is off his plate, so he's ready to go save Chuck's mom. Morgan picks up a huge gun. Casey tells him that he's not coming and to focus on his twinkle lights.

In Colombia, Chuck, Sarah and Casey get off a bus dressed for a jungle trek. Casey observes the heightened security around a nearby mine and suggests they investigate. They sit down at the mine cafe and Sarah orders the specialty of the house. Casey notices that there are two entrances to the mine, and the miners go in one, the guards in the other. He thinks Volkoff's base is in that cave. Sarah adds that Mary is probably being held down there. Chuck is ready to go in when the waiter brings a platter of horrible-looking dead animals. Casey sees the guards leaving and says they've got to move.

Chuck, Sarah and Casey head toward the mine entrance and quickly overpower a pair of guards. Chuck and Sarah don the guards' clothing and begin marching a handcuffed Casey into the mine. But they're stymied when a guard refuses to assign a cell for Casey without proper paperwork. Chuck pulls the guard aside and explains that he's hoping to impress Sarah by roughing up their prisoner. Chuck slaps Casey. The guard goads him on. Chuck punches Casey in the gut. After being prompted, Sarah agrees that it was sexy. The guard then gives them the keys to cell 24, commenting that Sarah looks like she's been there before. Chuck knocks him out.

Casey tells Chuck and Sarah to go find Mary and he'll catch up after he gets the guard's uniform on. Sarah sees on the monitor that Mary is in cell 13. They rush to Mary's cell, where Chuck hugs her. Mary explains that she's not leaving without The Norseman. Mary suggests they leave; her plan is to endure a couple of rounds of torture and then steal The Norseman and find a way to break out. Sarah insists that they're not leaving Mary there to get tortured when they have a wedding to get her to.

Casey sticks his head in and says they've got to move. Mary insists that the wedding is important but so is the nation's safety, and if they move the weapon now, she'll never get it. Chuck announces the plan: he and Casey will go get The Norseman and Sarah will stay with Mary to make sure she doesn't get tortured. Sarah wants Casey to stay with Mary, but he says he's going with Chuck. Sarah's not happy about it, saying she'll stand guard outside. Casey and Chuck bust into the lab, but The Norseman is gone.

Chuck hacks into the lab's computer and sees that Vivian is planning a meet to sell The Norseman to the highest bidder, but he doesn't know where The Norseman has been moved to.

Vivian and Riley, aware that their operation has been compromised, approach Mary's cell. Chuck radios Sarah that the weapon's been moved, and they need Vivian alive so that she can go to the meet. Sarah orders Vivian and Riley against the wall and Mary disarms them. Vivian finally realizes that Mary is Chuck's mother. Chuck, Sarah, Casey and Mary move out, locking Vivian and Riley in the cell.

Beckman summons the team to Castle. She tells them that Vivian is planning to auction off The Norseman in Moscow in 12 hours, so they must strike now. Chuck wonders if someone else can go, since their rehearsal dinner is tomorrow. Beckman says there's no time to train a new team. Sarah wonders how they'll get in, given that Vivian knows all their faces. Beckman informs them that one of the invited buyers, Italian arms smuggler Etorre La Barba, was just detained. She shows them a picture of a bearded man in sunglasses and a stylish suit. He's got a familiar look - like Morgan. Casey says that Morgan isn't prepared for an operation like this. Beckman insists that he fits the profile.

Morgan practices a bad, fake Italian accent. Casey thinks this is a horrible idea. Chuck questions whether Morgan is comfortable doing this. Mary assures Chuck that Morgan will be fine. She and Casey will provide him plenty of backup and Chuck and Sarah will stay back and get ready for the wedding.

At the Buy More, Ellie and Devon sit in recliners with popcorn as Lester, Jeff and Big Mike show them the video montage they made of Chuck and Sarah. It starts off sweet, then gets weird and disturbing. Ellie tells Lester to stop. Ellie demands the footage and says she's taking over from here. Big Mike wants to know if he still gets his 10%. Devon informs him that they weren't paying Lester and Jeff.

At the armory, Morgan practices his accent again with Casey. It's still terrible. Casey says that if he had his choice, Morgan would be upstairs selling microwaves. Morgan's offended, but Casey reveals he's just concerned about Alex - who's worried about Morgan. Casey says that he promised Alex he'd keep Morgan safe, and if anything goes wrong, he'll have broken a promise to his daughter. Morgan promises that everything will be fine and nothing will go wrong, then kicks himself for saying that.

Casey and Mary set up their guns on a rooftop and radio in that they're in position. In the van, Morgan confesses to Chuck and Sarah that he doesn't know if he can do this. Chuck gives Morgan a pep talk, reassuring him that they'll be with him the whole time. Sarah adds that Casey will be on the opposite roof with a sniper rifle. Morgan heads into the Volkoff Headquarters conference room where a group of nasty, mean villains sits. Morgan does his best to appear tough.

From the van, Sarah reports that the thorium signature has been detected, and it looks like they're bringing in The Norseman. Vivian and Riley enter the conference room. Vivian describes The Norseman's DNA-targeting capabilities, then announces that the weapon is an advantage she intends to keep; she dispatches the would-be buyers one by one. Morgan asks Casey what to do over comms. Casey tells him that he has to die, or they'll kill him. Like the others, Morgan clutches his ears and falls over, as though dying.

Casey doesn't have Riley in his sights anymore. Chuck tells Morgan not to move. Vivian's man Riley announces that someone in the room is playing dead. An Englishman named Carlisle pops up and starts bragging about how he's been tracking them since Munich when BANG! Riley shoots him dead. Riley apologizes to Vivian and promises the next one is hers. Vivian and Riley leave with The Norseman. Mary goes in to secure the weapon, telling Casey to stay and keep "Alex's boyfriend" safe.

Casey tells Morgan to get out and Casey will cover him. But a terrified Morgan reports that a cleaning crew is coming in - and they have acid. Morgan's trapped on the conference room table, surrounded by Cleaners. Casey tells Morgan to show him the targets with his glasses and try not to move. One by one, Casey takes out the targets.

Chuck and Sarah see Vivian and Riley leave the building. Chuck backs the van up to intercept them. He crashes into their vehicle. Sarah detects the weapon in the trunk. Chuck checks to see if Vivian is all right. Vivian interrupts and tells Chuck that she knows he's Agent X. Chuck corrects her and informs her that Agent X is her father, who was an MI6 agent who went undercover and let the CIA perform an experiment on him. That experiment changed him into the man they know now as Alexei Volkoff. Chuck tells Vivian that her father wasn't evil, and neither is she. Riley emerges from the car and points his gun at Chuck. But he's soon cut down by Sarah.

All dressed up, Devon finds an unhappy Ellie in the courtyard. Ellie shares that she dropped the ball on Chuck's present to Sarah because she fell asleep while she was cutting it. Devon reassures Ellie that she did what she could, and it'll be okay. Chuck and Sarah walk into the courtyard. They thank Ellie for making the courtyard look so amazing. Chuck asks Sarah if she's ready. She is.

At the rehearsal dinner, Morgan tells Casey that he agrees he shouldn't be out in the field if it's going to make the woman he loves worry. He tells Casey to tell Alex that Morgan is out of the spy game. Casey sees Alex approach from behind and tells Morgan he can tell her himself. Alex confesses that she loves Morgan. He responds that he loves her, too.

Mary clinks her glass to give a toast. She admits that she was gone from Chuck and Ellie's lives for a long time, so sometimes she overcompensates. Mary looks at Sarah and says that fortunately for her, her soon-to-be-daughter-in-law is very forgiving. Mary compliments Sarah for being a strong and amazing woman and toasts to her and to Sarah and Chuck having many adventures together and always keeping each other safe.

Chuck leans over and tells Sarah he has a surprise for her. Chuck goes to turn on the video. Ellie intercepts him to confess that she didn't finish it. But before Ellie can say anything, the music starts and the video is a sweet and romantic collection of photographs of Chuck and Sarah. Jeff approaches Ellie and Chuck and shares that Lester never let Ellie see his version and he hopes she likes it. Ellie kisses Jeff, freezing him in a happy smile.

As the video finishes playing, Chuck gets a call on an encrypted line. It's Vivian. She tells him that she wants to make him feel pain like she's feeling right now. Vivian tells Chuck to look around at all his family and friends and wonder which one Vivian is going to take from him. Vivian has another Norseman. Chuck begs Vivian not to do this. She says she already has and hangs up. Sarah approaches and asks what's going on. Chuck tells her that he thinks Vivian is going after his mom. Just then, Sarah clutches her ears and a drop of blood falls from her nose. Chuck realizes what Vivian has done and clutches Sarah, yelling for help.
