Lewis is talking to Venna, Leelee Sobieski on the phone, and the distance between their colleges feels suddenly wider than the miles that separate them. Venna reveals she and her boyfriend have just broken up, and she frets about needing a ride home. In a bid to seem capable and independent, Lewis fibs that he owns a car and could drive across the country to fetch her. The next day, fate nudges him toward reality: he buys a used car, a move that shifts the plan from fantasy to possible road-splitting truth.
Back at home, Lewis calls his mother to share the update and to lay out his next moves, only to receive unexpected family news. His brother Fuller has been arrested again. The weight of that admission lands hard, and Lewis agrees to make a stop and retrieve Fuller from jail before continuing toward Venna. The road ahead quickly becomes something more dangerous than a simple reunion, as minor bumps in the journey compound into a perilous chase.
A routine trip veers into trouble when Lewis finds himself hit with a ticket for an illegal traffic move and a broken tail light. The ticket is a banal annoyance in another story, but in this one it’s a prelude to trouble that won’t vanish with a warning. They pick up Fuller, whose irreducible restlessness adds fuel to the fire. The trio heads toward Venna, the sense of looming danger threading through the cabin like static in the air.
Fuller has a mischievous streak that soon spirals out of control. He buys a small, illicit upgrade to their highway life: a CB radio. At a gas station, he pays a man to rig the device so they can have a little “fun.” The prank begins as Lewis is instructed to pretend to be a seductive caller named “Candy Cane” looking for a night of company, while Fuller pretends to be the man answering the request. The whole setup starts as a joke, a game meant to pass the miles and spark a few laughs.
The prank rapidly escalates when another trucker, who calls himself “Rusty Nail,” replies to the ruse. The mischief grows darker as Fuller and Lewis push the joke further. The plan unfolds with a motel stop that night when Rusty Nail’s calls intensify, and Lewis is told to meet the supposed date in Room 17, with a bottle of pink champagne left behind as a taunting sign. The moment feels absurd and dangerous at once, a cruel prank that could unfurl into violence at any misstep.
By dawn, the aftermath of their misadventure lands squarely on their shoulders. The next morning brings questions from the police; the man next door has been attacked, jaw ripped off and thrown onto the highway, leaving him in a coma. The cops are furious and make it clear they will have nothing to do with their improvised highway saga. They tell Lewis and Fuller to leave the state and never come back, a stark rebuke that marks the moment when their casual prank becomes a flight from consequence.
The road grows still more surreal as the radio calls resume. The trucker behind the “Rusty Nail” moniker keeps pressing for a meeting, but Fuller’s attempts to smooth things over crumble under the weight of fear. The prank’s supposed humor dissolves into real tension, and the brothers realize the situation is spiraling toward something far more dangerous than a bad joke.
A strange encounter with an ice truck driver at a gas station adds another layer to the chase. Lewis, trying to stay ahead of the danger, pays for gas and pockets the memory of that stop as a small victory in a rapidly tightening vice. The ice truck driver’s arrival seems almost incidental, but it anchors the sense that help can arrive from the most unexpected corners.
They pick up Venna at last, and she introduces them to her roommate, Charlotte, who is driving away toward home. The night unfolds with a trip to a bar where Venna finds herself harassed by a man. Fuller stirs the pot once more and they flee back to Venna’s room, trying to steady their nerves amid the growing chaos. Lewis falls asleep, while Fuller slips back to Venna’s room for another round of drinks and laughter that feels increasingly hollow in the face of looming danger.
The phone rings back in Lewis’s room. It’s Rusty Nail, taunting them with the cruel line, “I thought there was no Candy Cane.” The truth erupts: the man knows who is in the room with Fuller. Lewis darts toward Venna’s room, their plans of calm dissolving into panic. Venna’s fear escalates as the trio packs and blasts off into the night.
The road signs start to spell out a hidden instruction: “Look in the trunk.” Fuller pulls over and they discover the CB radio has to be reconnected. They drive toward a diner where the chase intensifies and Venna’s roommate Charlotte is ultimately kidnapped by the trucker. The plan shatters as fear becomes a practical threat, and the trio realizes they are being maneuvered into an elaborate trap.
To complicate matters, the menacing “Rusty Nail” forces Lewis and Fuller to walk into a diner naked and order six cheeseburgers while Venna remains in the car. The sight of their nakedness is shocking, but the real danger is elsewhere. They escape the diner and dash into a corn field, walking about 100 paces as instructed. The plan, however, misfires when a speeding truck appears, and Venna is forcibly taken, her screams crackling over the CB radio and turning the chase into a race against an invisible clock.
With Venna in peril, the trio races toward a hotel at a truck stop, room 17 again becoming the stage for a deadly game. The killer’s reach seems everywhere; the walls hum with the sound of his malevolent presence as he speaks through the radio, promising more if they fail to cooperate. The fear is palpable, and the tension tightens with each door they knock on in search of Venna.
In this terrifying game of cat and mouse, Fuller is pulled into a trap that is as physical as it is psychological. The killer’s plan hinges on a cruel show—the trucker’s violent insistence that the hunt remain private and that the “joke” be stretched to its limit. The car explodes in a moment of chaos, and the chase bursts into a dangerous, window-rattling confrontation. The police arrive, the hotel is thrown into disarray, and the trio fights for a way to rescue Venna and survive the night.
As the dust settles, the immediate danger shifts from the road to the hotel’s interior. The cops move through the rooms, guns drawn, hunting for the source of the terror. Fuller is injured, and Lewis scrambles to rescue Venna before the authorities inadvertently hurt her in the process. The trucker’s shadow looms large, but a rapid, desperate effort yields a partial escape: the truck is stopped, the killer’s trail seems to vanish, and the room where Venna was kept appears abandoned.
The aftermath reveals a grim twist that leaves Lewis and Fuller staring at a stranger’s watch—one that matches the killer’s—found in the back of the ice truck. The person whose voice haunted the CB radio turns out to be a man named Jones who works for an ice company, a revelation that shatters their certainty about who was pulling the strings. Yet the danger isn’t over; the killer’s voice crackles through the radio one last time, reminding them that he’s not truly gone.
In the end, Charlotte and Venna reunite with relief at the ambulance, and Lewis, with Fuller at his side, processes the night’s horrific events. The police piece together the night’s chaos, but the final note remains: the mystery of Rusty Nail endures, his presence lingering in the faint crackle of the CB radio, a reminder that some threats don’t vanish even when the immediate danger has passed.
