Eden Murphy, a bright and ambitious high school student, dreams of securing a scholarship to Pembroke University. Currently on the waitlist, she believes that getting the support of Barrett Schroder, the son of a powerful congressman, could be her ticket in. In her pursuit, she politely approaches Barrett and requests a meeting with his father, but her request is brushed aside, leaving her feeling frustrated and desperate.
Determined to make a difference, Eden enlists her friend Zara and heads to Barrett's extravagant Heaven and Hell party at his luxurious mansion, hoping to strike a deal or at least catch his attention. They are dropped off outside by Eden’s father, who struggles with mobility and needs back surgery, adding a layer of concern for her family’s circumstances. Once inside, their phones are confiscated by Barrett's friend Kendra to ensure privacy, which complicates their plans but doesn’t deter Eden.
While Zara distracts Gooch—a friend of Barrett’s—Eden manages to connect with Barrett himself during a lively game of beer pong. The party takes a dark turn when a girl claiming to be the sister of a missing student Melissa arrives, demanding answers about her sister’s whereabouts. This disturbance prompts Eden to take the girl home in Barrett's car, exhibiting her resourcefulness. When she returns, Barrett unexpectedly invites her into a private room, where she shares her scholarship pitch. Impressed, Barrett invites her to a beer pong match, during which Eden takes the opportunity to help her friend Zara, who is drunk, by escorting her to bed.
As the night progresses, Eden discovers something alarming—she finds Gooch in bed with Zara, passed out, and upon examining his phone, she uncovers disturbing videos. These videos show Barrett, Kendra, and Gooch harassing Melissa to get her drunk before her disappearance; the footage abruptly stops due to a low battery. This discovery reveals the sinister behavior of the party’s hosts, and Eden’s shock deepens as she realizes their potential involvement in Melissa’s case.
Gooch, in a panic, blames Barrett and Kendra when Eden confronts him. As they try to force their way into the room, Eden blocks the door with a wardrobe, refusing to let their malicious actions be hidden. Meanwhile, Barrett violently forces everyone out, allowing Eden to grab a phone charger in her attempt to document what’s happening. Her plans are threatened when Gooch, now frantic, and Zara, confused and sleepy, are caught off guard. Zara unknowingly lets Gooch into the bathroom, where he threatens Eden to hand over her phone. The girls manage to overpower him, trapping Gooch in a bath of water, aiming to stop him from causing further harm.
Things escalate when Barrett, wielding an axe, and Kendra break into the room. Eden and Zara quickly lock themselves inside the bathroom, threatening to electrocute Gooch with a hairdryer. Their plan to get help fails when Zara’s attempt to escape out the bathroom window is thwarted—Kendra, in a final act of tragedy, is impaled on a blade on the ground as she clings to Zara. Eden then makes a desperate attempt to contact help using Kendra’s phone, but she is chased back inside by Barrett, who has discovered Kendra’s body. The situation spirals into chaos, leading Eden to explain everything to Zara.
Suddenly, Eden’s father arrives looking for her, only to be attacked by Barrett, who demands she hand over the phone. In the chaos, Zara throws the phone towards Eden, but soon the situation takes a darker turn when Congressman Schroder and his wife Astrid arrive at the mansion, trying to contain the mounting crisis with bribery and intimidation to keep their secrets safe. Eden insists on seeing more footage before deciding what to do next, uncovering further evidence of Barrett’s violent tendencies—specifically, that he ran over Melissa with his car and disposed of her body.
The horrifying truth leaves Eden devastated, and she resolves to take justice into her own hands. She attempts to leave with Zara, but the Schroder family’s influence is overpowering—drugs in their drinks render her unconscious, and she wakes up in a car with the bodies of Gooch and Kendra, along with her father. In a cruel betray, the Schroders push her and her companions into a lake, mirroring her father’s tragic death earlier. Although she manages to escape with Zara, she is overwhelmed by grief.
Fuelled by anger and grief, Eden returns to the mansion for revenge. She kills Congressman Schroder with an axe and fights Astrid, leading to a violent confrontation that ends with Eden electrocuting her in a bath of water. Meanwhile, Barrett comes home, armed with a rifle, and quickly finds his family dead. He tries to run over Eden with his car, but she survives and faces him unarmed. Although she hesitates to shoot him and is overwhelmed with emotion, Zara intervenes by hitting Barrett in the back of the head with the rifle.
As sirens approach, the scene is filled with reflection on the night's darkness and violence. Eden, scarred but resolute, stands amid the wreckage, knowing she has taken justice into her own hands, determined to ensure that the truth is never buried.
