The party is hosted by his daughter Samantha (Kelly Noonan), and is attended by his long time friends and co-workers Mundy (Brent Briscoe), Masek (Eric Etebari), Torres (Kurt Caceres) and Randy (Joey Kern). As the party winds down Samantha enters into a challenge to see if she can handle a single day in the mines, something that leaves a few of the men apprehensive at it's considered bad luck to have a woman in the mines. Samantha takes the challenge and goes with her father the next day to his last day at work. Samantha is put under the care of Randy, a former paramour of hers. But things quickly go sideways when the crew breaks into a natural crevice in the mines wall causing a cave in. Now the miners are trapped in the mines and with rescue crews seventy-two hours away, the surviving miners take refuge in an emergency bunker that has enough oxygen and food to keep them alive until help arrives. But, when the men hear calls for help and venture into the mines fearing it to be one of their missing men. They start falling victim to insanity and violence, violence that escalates until the miners are forced to find a way out of the mines or die
