The Creature of the Mountain (None of them expected what was coming...)

A group of friends goes up to the mountains for a special surprise celebration. They think nothing nothing of it as they've been to this cabin in the mountains every year for the past five years. Nothing has happened to them up until now, why would they think this year would be any different? But what happens when one thing changes? One suspicious person hanging around the cabin? Weird sounds from the woods? And one thing they never expected........What will they do when they meet The Creature of the Mountain?
