Childhood friends Dan Walker and Joe Lynch, accompanied by Dan's girlfriend Parker O'Neill, plan to enjoy a pleasant Sunday afternoon at a picturesque ski resort in New England. Eager to avoid the hefty price of three ski lift tickets, Dan persuades Parker to make a deal with the ski lift attendant, Jason, to let them on the lift without paying in full. As they ascend the mountain, an unexpected malfunction causes the ski lift to briefly stop, only to resume shortly after.
During their time at the resort, they watch in amusement as Parker struggles to maintain her balance on the snowboard. However, as evening falls and a looming snowstorm approaches, the resort decides to close early. The trio reminds Jason of their earlier agreement, successfully negotiating one last opportunity to ride up the lift before closing. Just before they reach the summit, Jason is abruptly replaced by his colleague, Rifkin. Unbeknownst to them, their ride is about to take a treacherous turn; upon spotting a new set of skiers, Rifkin makes the call to shut down the lift, leaving Dan, Joe, and Parker stranded high above the snowy landscape.
At first, the friends are simply puzzled, believing the shutdown to be a minor technical issue. But as darkness envelops the mountain and the blizzard sets in, their anxiety escalates. After a while, hope seems fleeting when a snowcat nearly approaches their chair, only for the driver, Cody, to receive a last-minute call back to base. Hours stretch on with no rescue in sight as the group realizes they could be left suspended in the freezing cold for an entire week until the resort reopens.
In a desperate bid to survive, Dan resolves to leap from the ski lift chair to find help, but the attempt results in a devastating compound fracture in both of his legs. In a chilling moment, a wolf approaches him, growling hungrily, but Parker courageously throws her snowboard at it, causing the creature to retreat. The tension escalates further when Joe decides to scale the ski lift cable to get closer to Dan. However, after a few painful feet, he is forced to return, hands bloodied and fraught with fear for his friend's safety. Tragically, Dan finds himself surrounded by a pack of wolves, who mercilessly attack him, leaving Parker and Joe horrified by the gruesome turn of events.
As morning breaks, Parker wakes to find her hand painfully glued to the ski lift’s safety bar, and in a agonizing effort, she pulls it away, sacrificing skin in the process. Meanwhile, frostbite begins to mar her face. Hours later, Joe attempts another climb, ultimately managing to descend safely two chairs down. However, the danger is far from over; Parker's chair begins to loosen dangerously from its supporting cable. In a gripping confrontation, Joe fights off a couple of wolves using a ski pole before desperately sliding down the mountain on Parker's snowboard, pursued by the ravenous predators.
Another night passes, and Parker remains alone, gripped by the chilling fear that Joe has met a terrible fate. Determined to escape, she plans her own jump down from the ski lift but endures a painful fall when the chair drops unexpectedly. Injured yet resolute, she slides and crawls down the treacherous mountain, only to find evidence of Joe’s demise, leaving her utterly traumatized.
Finally reaching safety, Parker makes it to a road where hope flickers back to life as a car stops to aid her. The driver, a man named [Peder Melhuse], calls the hospital, informing them that he found a girl injured outside the ski resort. The film concludes with echoes of reassurance as Parker hears Dan's voice, whispering, > "You'll be ok, baby. You're gonna be ok."
