As the sun blazes down on the gleaming shores of Malibu, a trio of skilled thieves—Casper, Dodge, and Iris—execute a daring heist under the clear blue sky with remarkable skill. Following their successful operation, Iris shares news of a potentially lucrative venture at a luxurious coastal mansion. However, the associated risks prompt the group to think twice about the dangerous plan.
Things take a darker turn for Casper when he learns that his father, Flash, has been abducted by the ruthless loan shark Emory. With Emory demanding immediate payment for Flash’s debts, a frantic Casper confronts him at his strip club, only to be met with cold indifference. Left with a dire ultimatum, Casper must now reconsider Iris’s original suggestion.
To infiltrate the opulent Dawson family mansion, the trio disguises themselves as caterers, where they encounter the intriguing Patrick and Roxanne Dawson along with their children, Elliot and Alexis. The energy inside the mansion is laden with tension, particularly with Roxanne exhibiting peculiar nervousness. Meanwhile, Casper engages in a covert exploration, discovering a safe that he believes holds the key to his plan alongside Iris and Dodge.
As the evening unfolds and guests begin to arrive, the atmosphere is punctuated with introductions from recovering addicts who gather to celebrate their sobriety. Among them are musician Ollie, Cameron, Jeremy, Milo, and his date Becca. However, the illusion of camaraderie is shattered when Elliot’s pent-up rage surfaces violently, resulting in a horrifying attack on Dodge, leading to his brutal demise.
With the mansion’s security systems momentarily down, chaos erupts as Elliot’s bloody outburst leaves the guests stunned. Amid the carnage, Iris rushes in, only to confront Dodge’s lifeless body, igniting a wave of fear and confusion. In a bold act of vengeance, Iris responds to the mayhem by confronting Ollie, leading to his deadly tumble down the stairs. As tensions mount, Milo attempts to regain control, dismissing violence but revealing the chilling truth about his group—a collective of recovering serial killers.
In the midst of chaos, Iris learns from Alexis about a plan to escape, but they soon face brutal opposition from Cameron and Jeremy. With a determined Casper rising up, he forces the group downstairs, culminating in a struggle as Jeremy attempts to silence Iris. In a flurry of violence where loyalties shift rapidly, the tension reaches its peak as Patrick’s malicious intentions grow more apparent.
Amidst the disorder, the homes intercom system broadcasts chilling taunts, leading to the revelation of Mikey, Dawson’s once-loving pet, now turned monstrous within the sealed chamber. A life-and-death struggle pursues, culminating in Iris’s tragic fate as she faces the beast’s fury. In a heroic conclusion, Casper finds the courage to confront and slay the creature.
In the aftermath, Patrick’s efforts to reinitiate control are thwarted as secrets unravel. The couple’s hidden room filled with sinister mementos becomes vital, leading to a dramatic escape with the secrets of the Dawson family looming large. With fights breaking out, alliances are formed, and revelation strikes—Roxanne shows her strength by elegantly countering threats amidst the pandemonium.
As restorative justice pursues Casper, he seizes the opportunity to crash into the world of Emory, executing his quest for vengeance with brutal efficiency. With the shocking climax leaving devastation in its wake, Casper’s chilling encounter with Emory not only seals his father’s fate but also sets Casper on a path of no return, in a story reminding us of the high costs associated with vengeance and retribution.
