After burning through a few days’ worth of room service on a train from Paris to Zurich, Chuck and Sarah confront the necessity to make a decision regarding their future, arriving at the conclusion that they should quit the spy life. The iPhone goes out the train window and the reinstated Casey immediately gets his first new assignment from Beckman: use Morgan to locate Chuck. As the lovebirds discuss where to begin their new free-wandering life, Chuck flashes on one of three very suspicious-looking men who seat themselves in the dining car: Juan Diego Arnaldo, a Basque ETA terrorist. Sarah raises her coffee cup. “To not being spies,” she toasts. Chuck instantly looks relieved and agrees. Sarah pilfers the table knife anyway, because she also recognized the terrorist.
Morgan discusses the task at hand with Casey and is interrupted by Awesome barging into the Buy More to warn him that if Chuck misses their going-away party it’s going to hurt her feelings really bad. Jeff and Lester hear the word party and invite themselves. Uh-oh, no, it’s worse — they hire themselves to provide music. Back on the train, Chuck and Sarah innocently go to bed mentioning to the other that they’re definitely not getting involved with any spy things since they’re free now. Then Sarah decides to go get some ice cream and Chuck decides to get some air. She goes down the hall (in her freaking underwear!), he out the window, both rifling through the terrorist’s compartment and missing each other in the process. Back in their own compartment a few minutes later, Sarah confesses that she recognized someone bad — and Chuck tells her he flashed on the Basque baddie. It would be irresponsible, they agree, to turn their backs on such a really bad guy. “One more mission,” they slyly agree, kissing.
In Burbank, Morgan’s expertise in all things Chuck enables Casey to determine where the fugitives are, and they depart to intercept the train. Jeffster blows out their amp rehearsing and Lester decides to do th
e party “unplugged” as Ellie and Devon look on in dismay. Ellie frets even more about not knowing where her brother is.
Her brother and Sarah are purloining the gear they need to take the bad guys down, as they left all their spy gear behind in France. Chuck appears to be in complete control of his flash act now. The pair slip mickeys to the terrorists but as they kiss back at their table, awaiting the bad-guy slump, Casey slips into the booth and slaps the cuffs on them, not believing their protest that they are on the trail of a terrorist. Two of the guys pass out but Juan himself hasn’t had his drink and makes his escape. The Charlses escape after him, Casey hot on their heels. At the end of the chase, they discover that the terrorist was being taken to a witness protection program by a pair of Interpol agents. Oops. At the same time, another passenger is revealed (only to us) to be trailing the terrorist, intending to kill him. Double oops.
A lot of Chuck fans who travel on business are at this point emailing the writers to find out how they too can cross the continent and the Atlantic in a minute thirty seconds. In coach. Seriously?
The team calls in to Beckman for backup. Beckman is not amused. The four of them are ordered to keep him alive until a new Interpol team picks him up. Chuck and Sarah take off following an admonition from Juan (huh?) to make sure it’s what they both want before doing it. While the pair heads for the train, and Jeff and Lester actually do a halfway decent job of singing “Leaving On A Jet Plane” half a world away, a new duo of agents arrives to take Juan off Casey and Grimes’ hands. As Morgan chatters to them about the scenery they make several factual errors that tip him off that they are not from Interpol. Too late, Casey draws. They have a lot of backup, and Casey and Morgan are outnumbered. Jeffster invites the guests of honor to say a few words to the crowd and Ellie, who has had too much to drink, heads for the microphone. Devon is (rightly) worried. Chuck and Sarah are about to board the train but they’re drawn upon by the agents they drugged earlier.
Chuck and Sarah escape from the Interpol agents quickly after failing to convince them of the mistake and hijack a scooter to back up Casey and Morgan. While they are still handcuffed, the duo takes out all fifteen (or five, it was kind of hard to tell!) of the bad guys and then realize they both want to keep the spy life and each other.
With the team back home, General Beckman congratulates Casey and Morgan. Her response to Chuck and Sarah’s gut-spilling: “Off the record, it’s about damn time.”
After the commercial break, Chuck manages to catch Ellie and send her away to Africa with the knowledge that he’s in Sarah’s good hands and the pair kick back to begin the new chapter of their life together.
