The fourth episode of "Nine Bodies in a Mexican Morgue" kicks off with the arrival of U.S. officials, their mission to interrogate Cora, the director of the aircraft company, concerning the enigmatic crash. It transpires that the plane was registered under a Miami-based shell company, coincidentally the very same entity where Cora is employed in Mexico. Suspecting foul play, the officials depart, leaving behind a cloud of uncertainty.
Later, Cora attempts to reach out, her fingers hovering over the phone buttons, as the camera transitions to the sound of a phone ringing eerily in the desolate wilderness.
In a parallel scenario, Kevin attends to Dan, uncovering tattoos adorning his back, silent witnesses to Dan's time spent behind bars. The tranquility shatters abruptly as Dan lunges at Kevin, sparking a fracas that Lisa ultimately halts at gunpoint. We come to understand that Dan, once a convicted felon with a string of offenses under his belt, had initially set his sights on Amy but found his heart unexpectedly captured by her.
As dusk descends, shrouding the surroundings in darkness, Lisa mysteriously vanishes. The heavens open up, drenching the landscape in rain, prompting the group to seek refuge within the aircraft's mangled remains. To their astonishment, they stumble upon millions worth of cocaine stashed within. Meanwhile, Amy, her mind consumed by hallucinations of a fleeting figure, disappears without a trace. While the search for her intensifies, Lisa is spotted, a solitary figure nested within the aircraft's hollowed shell.
In no time, Amy's figure looms, approaching someone with a gleaming knife in hand. Lisa, sensing impending danger, steps in swiftly to rescue Amy, yet fate deals her a cruel blow as she is swiftly felled by the enigmatic assailant mere moments later. At this critical juncture, Sonja unburdens her haunting past. Her life had been on the brink of joyous matrimony when her fiancé's life was cruelly cut short by a drug overdose. This tragic event spurred her travels, and now, her suspicions turn towards Zack. Memories flood back—Zack's eerie knowledge of the cocaine's exact price, and her chilling discovery: a clandestine stash of bullets, pilfered from Lisa's rifle, alongside a firearm that she now trains on him with steady resolve.
The revelation unfolds that Zack is an undercover agent with the DEA. His mission had entwined him in a web of intrigue, investigating Sonja, the plane, and the aviation company entwined in the sinister trafficking of drugs across borders. He confesses ownership of the gun but disowns the satellite phone discovered among his possessions. Pleading for credulity, he urges them to verify his identity through his wallet—only to find it eerily absent. Zack protests his innocence, insisting that he is the victim of a meticulously crafted setup, but Dan's swift action renders him unconscious, the drama suspended in a tense limbo.
Later, Sonja endeavors to intercept a code from the radio, convinced it belongs to Zack, but her efforts prove futile. Consequently, she, Amy, and Dan resolve to inspect the GPS installation. Meanwhile, Kevin initiates an intense interrogation of Zack regarding the radio code, resorting to brutal tactics when Zack claims ignorance. In the concurrent timeline, American officers intercept a signal they believe to be emanating from Zack. Among them, Claire makes a daring decision to venture into the Mexican jungle in search of him, disregarding the diplomatic constraints that officially prohibit a search-and-rescue mission.
Switching back to Kevin and Zack's harrowing scenario, Kevin's torture escalates, his determination to wrest the code from Zack unwavering. At this critical juncture, a revealing twist unfolds: Zack is revealed to be Claire's husband. The episode concludes on a cliffhanger, with a shadowy figure approaching Zack, a gleaming knife in hand, heightening the suspense and intrigue.
