The movie opens with a woman receiving a distress call from a 'cop' reporting intruders. Panicked, she rushes to her daughter, only to find later that the call was a prank. This prank led to the woman accidentally shooting her own daughter and then herself, revealing the devastating impact of the teenagers' actions.
Teenagers Sam and Brady revel in making prank calls and uploading them online. During one session, they receive a call from an unknown individual, 'Mr. Lee,' who expresses disapproval of their actions and warns them of impending consequences. The boys initially dismiss him, but Mr. Lee begins to demonstrate knowledge of their personal details, raising their concern.
Mr. Lee's threats escalate, revealing he knows their names and addresses. He orchestrates a situation where Sam's girlfriend, Peyton, delivers pizza to their house. Later, Mr. Lee reveals he is holding Brady's parents captive. Despite their fear, Sam and Brady try to call the police, only to find Mr. Lee intercepting the calls. Mr. Lee then broadcasts the murder of their friend, Roy, and later, Mosley, setting a terrifying tone for the night.
Mr. Lee forces Brady into a dark deal while Sam is lured away. Sam discovers Mosley dead, having been suffocated. Mr. Lee then pressures Sam to kill Brady as a condition for Peyton's release. During this tense moment, Sam discovers that Peyton has been cheating on him with Brady, and Brady secretly recorded it, fueling Sam's rage.
Sam realizes some of Mr. Lee's videos are pre-recorded, and briefly considers killing Brady before freeing him. Mr. Lee then reveals he had already killed Brady's parents. Brady locks Sam out of the house to confront Mr. Lee, while Sam rushes to rescue Peyton. In a horrific twist, Sam accidentally stabs Brady, who was disguised as Mr. Lee. Mr. Lee, the grieving father from the opening scene, reveals his motive is revenge for his family's destruction. The film concludes with Sam being framed for all the murders, as news reports falsely accuse him of a jealous rampage.
