Murder Drones Season 1, Episode 4, "Cabin Fever," plunges viewers into a
twisted tale of horror, obsession, and the dark secrets lurking within the
characters. The episode begins with Uzi and her class embarking on a field trip
to Camp 98.7, an abandoned research facility turned campsite. Prior to the trip,
Khan reveals to Uzi that her late mother, Nori, had worn the same collar as
Doll's mother. Nori, it seems, knew about the Disassembly Drones' arrival and
convinced Khan to build the protective doors.

Driven by a desire to uncover the truth about her mother's connection to Camp 98.7, Uzi enlists N and V to accompany her as camp counselors, providing a distraction for the other students while she sneaks off to investigate. Uzi's exploration leads her to an abandoned building, where her body begins to overheat. Desperate for relief, she consumes the oil from a severed drone arm, a decision that will have dire consequences.
V, suspicious of Uzi's actions, makes it clear that she won't hesitate to kill her. However, Uzi's encounter with a squished robot bug takes an unexpected turn. She repairs the bug, known as the keybug, which leads her to a dead Worker Drone beneath the floor, surrounded by drawings eerily similar to her mom's. The keybug scans Uzi's face and reveals itself to be a key for an elevator.
Uzi's attempt to get N's attention without alerting V backfires, resulting in one of the students accidentally shooting an arrow towards her. Uzi, using her Absolute Solver powers, stops the arrow but causes it to mutate into an organic mass. Fearing for her safety, Uzi retreats to an abandoned cabin, where her body begins to overheat once again. She uses her powers to destroy the cabin's lights, but one of them starts to mutate, signaling the growing darkness within her.
N, concerned for Uzi's well-being, convinces V to stay at the camp while he goes to search for her. N discovers several footprints leading to an abandoned building and enters, stumbling upon a VHS tape labeled "Zombie Drones." As N approaches the tape, a series of memories flash before his eyes, revealing hidden truths about his past.
Meanwhile, two campers, Rebecca and Darren, sneak away from the group and stumble upon the cabin where Uzi is hiding. Their curiosity leads to a terrifying encounter, as Uzi, now transformed into a monstrous, organic-like Disassembly Drone, begins slaughtering the other campers.
Uzi's rampage reaches a climax when she attacks Lizzy, her former tormentor. V intervenes, calling Uzi by the name "Cyn" and preparing to kill her. In a brutal battle, Uzi overpowers V, but before she can deliver the final blow, N arrives and flings Uzi into the air. As Uzi falls, she is overcome with guilt and remorse for her actions.
N, seeing Uzi's suffering, reassures her that they will figure out what is happening to her. When they plunge into the ground, Uzi transforms back to normal, escaping the clutches of her monstrous form.
As the remaining students prepare to leave, V covers for Uzi, claiming that she was responsible for the missing campers. The teacher, unconcerned with the truth, allows them to leave without further questioning.
Heading back to the colony, N notices Uzi's hand burning under the sunlight and instinctively moves it away. His gaze falls upon the VHS tape he brought back, and he stares at it with a mixture of fear and anticipation, knowing that the truth about their past lies within.
