The episode kicks off with Harmony Cobel (portrayed by Patricia Arquette) venturing into the quaint yet eerie town of Salt's Neck. Hardly have her footsteps echoed within the town's confines when she pauses by the roadside to freshen up, her toothbrush clinking against the porcelain. Amidst her routine, her gaze catches a disturbing sight: an addict, hidden in the shadows, inhaling something mysterious from a crumpled brown paper bag. Just as she digests this grim tableau, her phone buzzes with a missed call from Devon Scout-Hale (Jen Tullock), its timing almost uncanny.
Abandoning the troubled scene, Harmony strides into a local diner, where she's immediately greeted by a waiter who recognizes her as if time had never separated them. After a nostalgic exchange, she leans in, confidentially requesting a favor—a ride to the factory. He hesitates, curiosity piqued yet cautious. She persuades him by hinting that her presence might arouse suspicion if they were indeed monitoring the place, her vehicle being too recognizable. When he inquiries about the nature of her request, she reminisces about their past camaraderie, a bond that eventually softens his stance.
With Harmony concealed beneath a tarp in the truck's bed, the journey begins. Her tranquility is momentarily shattered by another call from Devon, which she decides to ignore for the sake of urgency.
Upon arriving at the house, Harmony springs up the stairs like a woman possessed, her destination the top bedroom. Sissy Cobel (Jane Alexander), waiting downstairs, warns her that neither she nor the addict have a place there. Harmony, undeterred, claims responsibility for igniting the addict's destructive path. Sissy retorts with accusations of deceit. The bedroom, upon Harmony's arrival, stands eerily barren. Disheartened yet persistent, she descends to confront Sissy once more, inquiring about the fate of her belongings. Sissy reveals a chilling truth: they've been pawned off on the less fortunate.
Harmony's voice hardens as she demands the key to their mother's room, a sanctuary now closed off. Sissy, steadfast, responds cryptically, stating that the room will remain vacant until all who cherish their mother's memory sit in the presence of Kier Eagan (Marc Geller), a figure wrapped in mystery and power.
It is further disclosed that Sissy allowed their mother to pass away as a compassionate act to alleviate her relentless agony. Harmony laments that if her studies hadn't been a priority, she would have been by their mother's side, offering care and comfort. Sissy informs Harmony that Mr. Eagan saw a glimmer of Kier within her, yet still labels Harmony as a disappointment. However, Sissy hints at a glimmer of hope, mentioning that if Harmony were to return and earnestly seek forgiveness, the Eagan family might just reconcile with her. Nonetheless, Sissy steadfastly refuses to hand over the key to their mother's room, prompting Harmony to embark on a desperate search for it upstairs.
Harmony eventually stumbles upon the key and makes a hurried beeline for her mother's chamber. She collapses onto the bed, tears streaming down her face as she breathes in the oxygen her mother once depended on. Her heart-wrenching sobs echo through the room for an extended period until exhaustion finally claims her, and she drifts into a restless sleep.
Harmony's slumber is abruptly interrupted by the waiter, who informs her that he must depart soon. She urgently conveys the need to find something before leaving, though she remains cryptic about her search. He confesses that he held a fondness for her mother, despite acknowledging her aversion to Lumon as the sole basis of his affection. The waiter, pulling out a small glass vial and cloth from his pocket, offers Harmony a hit of a substance, mimicking the actions of a homeless man she had previously observed. Tempted, Harmony accepts and indulges, feeling the effects instantly.
Harmony, ashamed yet intrigued by the waiter's dealings, kisses him passionately. Following their lip-lock, he doubts that what she seeks lies within the confines of the room. She insists on keeping her quest alive and ventures outside to a dimly lit cellar. Inside, she discovers a bust of Jame Eagan (Michael Siberry) and, using a screwdriver, meticulously pries off the base. To her amazement, she uncovers an ancient, rolled-up notebook, its pages yellowed with time. With her prize in hand, she exits and instructs the waiter to prepare the truck.
Before departing, Harmony takes a moment to re-enter the building, urging Sissy in a hushed tone never to reveal her presence. She confides in Sissy that Lumon had razed their town to the ground, eradicating any obligation she might feel toward them. In response, Sissy contends that Lumon preceded any semblance of a town and that everything Harmony possesses is due to Lumon's benevolence. Harmony then unveils the contents she retrieved from the bust, revealing them to be her own designs. Sissy, initially skeptical, inspects the blueprints and is astounded to find the book brimming with Harmony's creative genius. She inquires why Harmony has kept this a secret, to which Harmony replies that she was warned that seeking recognition would result in exile. Attempting to expunge the evidence, Sissy tosses the notebook into a wood-burning stove, but Harmony snatches it from the flames at the last moment. With venom in her voice, Harmony诅咒 Sissy a painful death, mirroring that of her mother's. Sissy retaliates harshly, revealing that Harmony's mother had removed her life support out of cowardice. Harmony, refusing to accept this truth, is interrupted by the waiter's blast on a horn, announcing an incoming visitor.
Outside, the waiter hands Harmony the keys to his truck, urging her to make haste. She gazes at him, recognizing him as Hampton, who reassuringly bids her farewell with the promise of future encounters. As Harmony climbs into the truck, her phone buzzes with another call from Devon. This time, she answers. Devon informs her of Mark Scout's (Adam Scott) reintegration, prompting Harmony to demand to speak with Mark directly. With urgency, Harmony implores Mark to recount everything, and the episode concludes on this cliffhanger.
