When Slater convinces his family to stop at Arrowhead Trail on Malridge Mountain on the way to his aunt and uncle's house, he's disappointed when his younger brother's complaining quickly ends their hike. But Slater figures he can take a quick hike up the trail before his family is ready to leave the next morning. However, Slater's hike up to a beautiful view becomes a disastrous trip back down when he tries to recover his dropped cell phone and can't get back on the trail. To get back to his family, Slater will have to work his way down the mountain battling bad weather, hunger, a few falls, and one close encounter.
