Twilight Sparkle is told by her friends to stop studying for a week and go on their annual camping trip with them to Camp Arawak Lake. She is nervous to go at first but after hearing her friends rave about it so often, her curiosity gets the better of her and she agrees to go on the trip to the delight of her friends. Little does she know that sompony else is going too. A pony that does not have the group's best interests at heart, and the results will be deadly.

Twilight Sparkle will be forced to use all of her wits and abilities if she is to survive the trip, but is survival even an option?
