Episode 3 of "Nine Bodies in a Mexican Morgue" unfurls on the third day following the survivors' harrowing plunge into the unforgiving Mexican wilderness. As the narrative progresses to the ninth day, a scene unfolds where soldiers converse about Carlos, a renowned freestyle wrestler whose name resonates with glory in the ring. The camera then seamlessly transitions to Carlos, who, with the dying breath of his phone's battery, rewatches his final match—a brutal defeat where he was outmatched by a fierce rival.
Flashing back to the third day, Carlos, Kevin, and Sonja team up to mend the aircraft's GPS system, venturing to a higher elevation to improve its reception. As they ascend, Sonja nearly loses her footing, her life momentarily hanging by a thread until Kevin and Carlos swiftly intervene. In this perilous instant, Sonja stumbles upon a startling revelation: Carlos has been surreptitiously pilfering from the group's dwindling food supplies.
Elsewhere, Lisa's paranoia grows like a cancer within the camp. She insists, with increasing fervor, that one among them is guilty of the fatalities. Her suspicions hone in on Dan, and as Amy, scarcely acquainted with him, catches wind of Lisa's accusations, she too finds herself wavering in trust towards him. Eventually, Amy unearths a shocking revelation: Dan may have a checkered past as a con artist. However, Dan vows to confide his full story to Amy.
Later, under the cloak of night, as Carlos engages in a rigorous workout, a shadowy figure sneaks up on him and delivers a fatal stab with a knife, plunging the camp into an even deeper shroud of fear and uncertainty.
The following morning, the group awakens to the startling realization that Carlos is nowhere to be found. Their anxiety deepens when the anticipated rescue team fails to arrive, despite the fact that a GPS tracker had been meticulously installed. It swiftly becomes apparent that the wires of Carlos' carefully set-up device have been brutally severed.
Driven by a need to uncover the truth, Kevin and Sonja resolutely trek back uphill to inspect the GPS unit. Along the way, they can't help but notice a murder of crows gathering ominously. As they delve deeper into the area, they stumble upon a harrowing sight – Carlos' lifeless body lying there in the wilderness.
Elsewhere, Amy continues to grapple with vivid hallucinations of a gun-toting man lurking in the shadows, firmly convinced that he has the group in his sights. In her disoriented and distressed state, she lashes out at Dan, leaving him with a fortunately minor injury. Upon their return, Kevin lends a helping hand to Dan as he tends to his wound. Dan confides in Kevin, revealing that Amy had survived a harrowing mass shooting as a child and has since battled with her mental health. It was during his time as her limo driver, taking her to a clinic, that their paths first crossed.
The group, already on edge, finds themselves wondering why they are being meticulously targeted. To add to their woes, they uncover Carlos' secret stash of stolen food. The episode draws to a close on an even more foreboding note, cutting to the falling night where we glimpse what appear to be illicit drugs concealed within the aircraft.
