Following a tumultuous film role that nearly derailed her career, actress Carol Cobb finds herself at a crossroads. She must face the daunting task of reviving her reputation by reluctantly stepping back into the shoes of the illustrious Dr. Lacey Nightingale for the latest installment of the beloved Cliff Beasts series, specifically Cliff Beasts 6: Battle for Everest: Memories of a Requiem. Despite her initial reluctance, this opportunity is crucial, as Carol had previously declined to participate in Cliff Beasts 5 to pursue a different project—one that turned out to be critically panned, where she portrayed a half Israeli, half Palestinian character battling extraterrestrial foes.
As production looms, Carol is haunted by the possibility that her former co-stars might hold grudges over her past choices, particularly Lauren, the only cast member who seems to harbor bitterness for Carol's abandonment. Overseeing the chaos is Paula, the studio executive managing the franchise's trajectory, while Gavin serves as the executive producer. The story unfolds during an unprecedented shoot, as the cast and crew congregate at a luxurious English hotel, forced into a two-week self-quarantine before filming due to the ongoing COVID-19 pandemic.
As Carol grapples with her mental stability, a welcome back party rekindles connections with her co-stars: Dustin, the relentless lead actor, Sean, who moonlights as a wellness guru, and Howie who provides comic relief. New characters emerge, including Dieter, a distinguished actor with a tragic role, and Krystal, a TikTok star brought in to attract younger audiences. The genial yet frazzled director Darren Eigan tries to navigate the chaos, all while managing the aspirations and demands of lead actors, especially the passionate Dustin.
As filming progresses, strange occurrences unfold: Howie succumbs to paranoia and quits, prompting the gruesome demise of his character. Meanwhile, Krystal and a production assistant venture into the city for a night of partying, only to face public backlash that threatens Krystal's online fame. The situation intensifies when the cast contracts influenza, but the studio pressures them to continue working, leading to a disastrous scene where everyone ends up violently ill.
Despite these setbacks, the cast's environment grows increasingly paranoid as Mr. Best, a mysterious figure, keeps tabs on them. Dealing with romantic entanglements and escalating chaos, Carol faces the shocking realization that her character's pivotal lines are being appropriated by Krystal. In light of brutal production realities and Lauren suffering a grisly injury, Carol confronts her agent Marti, who reminds her that she must complete the film contract or face enormous penalties.
In the end, the actor camaraderie is reignited as they bond over shared grievances and decide to escape the harsh confines of filming. A chaotic climax unfolds when Carol is pursued by Mr. Best, only to be saved by Howie's unexpected return. Their daring escape ends with a comedic helicopter ride helmed by an unprepared yet determined Sean, leveraging TikTok tutorials for guidance.
Fast forward two years, a documentary titled Beasts of the Bubble detailing the misadventures of the film’s production circles the globe, earning enthusiastic reviews. Carol may be labeled as the "villain" of the film, but she gleefully takes pride in what they accomplished together during that rollercoaster experience. Meanwhile, Dieter and Anika’s romance thrives, and Lauren adjusts to her new robotic hand, evoking a spirit of resilience among the cast members.
