At a chaotic wartime ceremony, Sierra—who suddenly woke as the unloved wife of Ethan Nacht—finds herself forced by the crowd to "marry a chicken" while Ethan is absent. Soldiers report an ambush meant to stop the wedding; captives are detained but Ethan is still away. Later, Leo falls down stairs and breaks his leg, and bystanders accuse Sierra of pushing him. Her protests are drowned out as elders demand retribution. The episode ends with Sierra facing interrogation and her father's looming decision, while someone asks, "Who is the ninth?"
On Ethan's return to Draconite Manor, Claire accuses Sierra of trying to snatch a necklace Felix bought and of pushing Leo down the stairs when he intervened. Bernard and Mdm. Clark back Claire and question Sierra's motives. Sierra denies the charge, insists the manor is her home and warns she won't be made homeless. When pressed for proof, Sierra says she has evidence and vows to reveal it using "modern tech." The household tenses as she prepares to present that evidence, leaving the dispute unresolved and everyone's loyalties in question.
At a meeting where Bernard demanded evidence, a woman presents a curious device she says a foreigner gave her. She claims it records and replays past sounds and admits she accidentally activated it after bumping into Claire and Leo. Commander Nacht is warned, "don't press it," but someone presses play and the device replays a voice. Leo utters, "Claire, that's your voice." The room reels as talk of foreign inventors and impossible microchips spreads. The reveal forces everyone to confront one urgent question: is Claire from a different era?
At a family gathering Claire, clearly drunk, is accused of seducing Leo despite liking Ethan and of framing Sierra. A witness threatens to expose her; Bernard is urged to seek justice for the injured Leo. Claire apologizes to Commander Nacht and Mdm. Smith, blaming alcohol, but Mdm. Smith rejects her and points to Leo’s broken leg. Sierra is labeled the victim and asked how to proceed, while others demand punishment. The episode turns when Claire’s failure to deny the charge hands control to Leo’s supporters; Dad declares 'an eye for an eye,' leaving Claire facing retribution.
On their wedding night at Nacht Estate, Ethan confronts his new wife after relatives mock her as a village girl and praise the 'ninth wife.' The bride refuses intimacy, fearing Ethan's flirtatious reputation and possible disease. Ethan alternates taunts with offers—saying he'll stay at the manor and that he knows how to handle village girls. When she resists, he presses on; she pleads, 'I haven't showered... I'm covered in sweat,' and begs him to stop. The episode ends with her frantic call for the ninth wife and a shouted 'Help me!', leaving her fate unresolved.
Someone discovers a packet of photos and accuses a woman of spying; she insists she only took a camera film from a follower a month ago when the Lowes brought her home. Interrogators press her—"You'd better be telling the truth"—threatening punishment if she lies. Flashbacks show she hid the film to develop. Meanwhile officers obtained confessions, named Commander Felix, and ordered the material held. A commander then demands Sierra's personal information after hearing Sierra may be the true heir. The episode ends with the film withheld and Sierra's identity now under active investigation.
Commander Ethan prepares to leave for Draconite Manor while Sierra finishes a task. The scene shifts when someone reports a planned explosion near Nord Mall: a time bomb is strapped under the target's car and a second cache of explosives is buried nearby. The report says the killer wants him blown to pieces, but a line claims Ethan has 'plot armor' and will survive, even be rescued by a so-called ninth wife. The speaker, who lacks that protection, panics at the impending blast and must scramble for safety as the car's departure approaches.
On her way out, a woman plans to fake a nasty fall and check beneath a car, wearing a cloak to cushion it. Commander Ethan's team then finds two time bombs under that vehicle and a cache of explosives near Nord Mall, which could have killed hundreds. Shocked she knew in advance, Ethan orders a full investigation and interrogations, suspecting a mole. The woman, hoping to act unlike the 'ninth wife' and avoid Ethan's interest, stalls him over her outfit — then blurts, 'Oh no. He caught me!' leaving her exposed and the bomb source unresolved.
By a car, someone struggles to check it and says, "I'll have to fall again" after a wet spot. A person apologizes and begs Commander Ethan; Ethan snaps, "If Mdm. Lowe fell because of you, you'd be dead!" Suddenly someone shouts, "There's a bomb!" The team is confused why it detonated here when Maple Street devices were already found and disarmed. They decide the device under the car must be allowed to go off here as the least risky move to avoid revealing prior knowledge. The episode ends with the scene set for that detonation.
Sierra Lowe, a genius at a future research institute, dies and wakes up a century in the past as Commander Ethan Nacht's fiancée. Her plan is simple: keep a low profile, earn money, avoid trouble, and step aside when the elusive ninth wife rises. On their wedding day her inner thoughts betray her. Ethan hears, loud and clear: 'So this is Ethan Nacht, the guy who secretly slept with the ninth wife?' The words shatter the ceremony. Ethan is stunned: 'Father only had eight wives. Where did the ninth come from?' Trust fractures instantly. Sierra must hide her origin and salvage her secret in a past that demands answers.
