Camping in the Colorado High Country can be a rugged affair unless you've got a 60-foot Class A motor home. Then it's easy street. That's what Paul Barnes and his wife, Sarah, think until a couple of murderous thugs on the lamb try to take it away from them. But the high-dollar carjacking goes wrong, a storm hits, and while trying to escape the killers, the rig gets stuck in the mud. Now under siege, Paul and Sarah hunker down, hoping a ranger comes along before they run out of food and water. Of course, that's not what happens, and an attempt to sneak away is thwarted by a rogue bear. Before this camping trip is over, somebody is going to die.
