Time Squad appears in medieval China around 1251, where Otto reminds the team that they are looking for Kublai Khan. Tuddrussel is too busy admiring blueprints for a new laser he wants in a magazine to pay attention when Otto suddenly hears voices nearby. Inside the palace, an old man is lecturing Kublai Khan, saying that he should be conquering places instead of reading comic books. Kublai ignores the man, who turns out to be his grandfather Genghis Khan, frustrating him. Larry and Otto are ready to speak with Kublai when Tuddrussel intervenes, saying that he has seen plenty of missions just like this, so he can handle this himself while Otto and Larry sightsee. Otto and Larry get talked into agreeing, allowing Tuddrussel to handle it Tuddrussel-style. He calls for Kublais attention, then rips one of his limited-edition comics, infuriating him.
Meanwhile, Larry and Otto are having fun exploring the local village and are getting photos of themselves taken by a peasant, when Otto suddenly sees a poster for Tuddrussels execution nearby. Larry plans to get Tuddrussel out of prison by dressing as an attorney and entering the prison, but he is denied entry, worrying Otto. Larry then says that he could call for emergency backup, revealing to Otto that there are more Time Squad officers working at any point in time. He hesitates at doing so, since Tuddrussel wont like it, but does so under pressure from Otto. He types on his arm, then lets out a distress signal.
A woman officer and a larger robot appear and this surprises Larry, and he mutters that Tuddrussel is REALLY not going to like this now. The officer is Sheila, and her robot partner is the XJ5. Sheila cooly greets Larry and asks what Buck has done this time. Larry explains that Tuddrussel got himself arrested and nervously introduces Otto as an orphan they "sort of adopted" (although Sheila calls it abduction) while XJ5 scans the prison with x-ray vision, locating Tuddrussel. He gives Sheila the information and she leaves to get Tuddrussel. She gets past the guards easily and finds Tuddrussel with radio assistance from XJ5. Tuddrussel is upset at Larry when he sees Sheila, and assures her that he was just about to bust out on his own. She frees him from his chains with a laser when they are suddenly attacked by ninjas who followed her. She and Tuddrussel battle them, while Tuddrussel tries to justify keeping Otto by calling him his nephew. She and Tuddrussel then scale the wall under fire from archers, who manage to hit Tuddrussels rear, and she informs him that she got a promotion to lieutenant, to his annoyance.
Later, after Tuddrussel is reunited with his unit, Tuddrussel insists that he can handle it from here. But Sheila reminds him that because they were called in for an emergency, Time Squad regulation states that she and XJ5 can't leave the mission until its completion. Down below from the cliff, Kublai Khan is seen riding with a military procession. Tuddrussel suggests that they all leave the mission since Kublai seems to be back to conquering when Kublai suddenly shoots a massive laser at a tree. Sheila asks Tuddrussel where he might have gotten a hold of such a device, and Tuddrussel realizes that Kublai might have found his magazine with blueprints for the laser he was looking at, and leaves to get it from him. Sheila lets down her guard when Tuddrussel leaves and mentions to Otto that at one point she and Tuddrussel were married and it obviously didn't work out, leading Larry and XJ 5 to chuckle amongst themselves over it.
Tuddrussel ends up getting captured by Kublai's army again. Exasperated, Sheila has XJ5 do something quick, and he sends out a dragon hologram, scaring Kublais men and scaring Kublai into dropping his weapon. Tuddrussel brings back the laser, which XJ5 and Sheila confiscate. Tuddrussel asks her to not mention anything incriminating or embarrassing in her report to headquarters, leading her to curtly say she'd think about it, and they leave without another word. Otto, shocked, expresses his amazement that Tuddrussel used to be married, making Tuddrussel upset and orders Larry to just take them home already.
Tropes present in this episode include:
- Action Girl: Sheila.
- Anachronism Stew: In-Universe example, Otto exclaims that he didn't know that comic books existed as early as the 1200's. Later, Sheila and XJ 5 point out that Otto doesn't look like he belongs in 13th century China, and wonder how Kublai Khan could have "possibly" got a hold of advanced weaponry like the laser cannon.
- Annoying Arrows: Tuddrussel gets hit with several arrows, providing Amusing Injuries up the butt.
- The Chosen Many: We learn that yes, there are more than one Time Squad units fixing history.
- Complaining About Rescues They Don't Like: Tuddrussel curses Larry for calling for help - especially when it was answered by his ex Sheila.
- Deadpan Snarker: Sheila, Larry, and XJ5 are all equally snarky to each other.
- Do-Anything Robot: XJ5 is far superior technology-wise, and enjoys rubbing in Larry's face.
- Embarrassing Rescue: Sheila has to rescue Tuddrussel from prison, and it's absolutely a mortifying event for him.
- Giving Radio to the Romans: Tuddrussel accidentally left his laser magazine where Kublai Khan could find it and use it to build his own laser cannon.
- Humiliation Conga: Tuddrussel gets arrested and is set to be executed; Larry calls on another Time Squad unit to help and who shows up? Tuddrussel's ex-wife. Sheila ends up busting him out and Tuddrussel is embarrassed that she had to save him. Then Sheila mentions that she got promoted to Lieutenant, making him all the angrier as soldiers keep shooting arrows into his butt.
- Manchild: Kublai Khan is so childish that he refuses to conquer land in order to collect comic books, much to the frustrations of his grandfather Genghis Khan.
- Photo Montage: While Tuddrussel is busy getting himself into trouble, Otto and Larry have a great time goofing off in town via photo montage.
- Sugar-and-Ice Personality: Sheila appears to be this, rather than a straight Emotionless Girl. The first impression you get from her is that she's cold and snarky, and that she could be a threat to the guys. But with the more you see of her, we get the understanding that deep down she's more kindhearted and understanding than she lets on and even goes out of her way to help out her ex-husband and not report him for all of the rules he violated. It's implied that the last time she interacted with Tuddrussel or Larry was probably during or right after the divorce and transfer to another team, which would understandably make things awkward for everyone involved.
