In a world filled with luxury, where designer possessions reflect immense wealth, Catherine Black (Gwen Van Dam), a shrewd corporate executive, conceals a chilling truth: she is a meticulous serial killer with a disturbing obsession for collecting human organs. Her next victim is Tyler Jones (Tyler Barnes), a crafty thief and gamer who has incited the wrath of Black's grandmother by stealing from her elderly acquaintances. When Jones visits Black's stunning Malibu estate under the pretense of wanting to house-sit, he unwittingly steps into a deadly trap.
After incapacitating him with a cocktail laced with a roofie, Black maintains her composed demeanor, even as she taunts him cruelly with the macabre remnants of a frat boy's organs, delivered in a mocking mix of Mandarin and twisted humor. The dark evening unfolds as Black and her girlfriend indulge in an erratic mix of debauchery, marked by drug use, sexual escapades, and a troubling bond.
However, the night takes a chaotic turn when an overbearing exercise partner irritates Black, provoking her to enact a brutal form of retribution. Once settled back at home, she orders Jones to vacate her estate. Yet, in a daring twist, he seizes the moment to escape, making off with Black's car and jewelry.
As Black utilizes a GPS tracker covertly planted in her stolen vehicle, she begins to uncover a web of thefts orchestrated by Jones and his accomplice, Chad. In a tense turn of events, Jones returns the stolen items in hopes of securing Black's silence. Nevertheless, Black's inherently treacherous nature proves irrefutable when she admits that keeping promises isn’t part of her character.
What follows is a harrowing physical confrontation that shines a light on the depths of Black's malevolence, revealing a chilling freezer stocked with human remains. As their conflict intensifies and an undeniable chemistry simmers between them, Black resolves to end Jones' life for good, yet their brutal encounters reveal a complicated bond that transcends mere attraction.
In a shocking conclusion to their fierce struggles, both Black and Jones agree to marry, signaling the start of an intricately chaotic chapter together. While Black attempts to suppress her murderous inclinations through medication, Jones turns away from his criminal past, committing himself to engineering studies and striving to make amends for his wrongdoings against Black's grandmother and other victims.
Together, they embark on a new life, embracing a vegan lifestyle while raising three children and a dog, all while trying to navigate the labyrinthine complexities of their tumultuous relationship.
