A prolific serial killer, who adopts the name "Aaron" in homage to one of his previous victims, finds himself beset by dissatisfaction regarding his own gruesome pursuits. As he grapples with a profound midlife crisis, Aaron's latest ad on an ideograph platform unexpectedly draws in a curious YouTuber named Sara to his isolated cabin. In a bold and perplexing twist, Aaron reveals his identity as a serial killer, proposing an unusual arrangement: he will grant Sara her life for the next 24 hours, provided she documents his existence on film.
Skeptical but intrigued, Sara reluctantly agrees, hoping this may ignite interest in her faltering web series focused on the quirky individuals she encounters through Craigslist. Throughout the day, the dynamic shifts as Aaron wrestles with his attempts to intimidate Sara, who cleverly navigates his eccentricities with a combination of doubt and composure. As the hours pass, Aaron's ominous intentions become clearer; he plans to conclude the documentary with a shocking finale – demanding that Sara end his life.
However, the situation escalates when Aaron stages a dramatic suicide attempt, momentarily pushing Sara to the brink of fleeing, only to discover that he had fabricated the peril he faced. The facade crumbles as they delve deeper into Aaron's psyche, with Sara eventually sharing a passionate kiss with the unnerved killer.
In a manic revelation, Aaron drags Sara outside, proclaiming that their documentary will culminate in a mutual suicide pact. Panic ensues when, in a shocking turn of events, he plunges a knife into his own stomach. In a desperate bid for survival, Sara attempts to escape, but Aaron unexpectedly turns the blade on her, pulling her into a grave he has prepared. As he delivers an ominous closing monologue, the story takes an unexpected twist when a seemingly lifeless Sara rises from the grave, striking him with a shovel from behind in a bid for escape.
Ultimately, the story doesn't end there. Sara's escape leads her into the public eye as an unknown figure records her without her knowledge, whistling a haunting melody reminiscent of Aaron's past videos. As tension lingers, the scene cuts abruptly, leaving viewers with an unsettling sense of mystery surrounding Sara's fate and the lingering influence of the villainous Aaron.
