It was Cozy Glow's first Nightmare Night in Ponyville. She had picked the ideal costume to represent her and she would spend the night with her new, best friends: The Cutie Mark Crusaders. And maybe, she could even find her second wing.
On Princess Luna's first Nightmares Night she wanted it to last longer. But when she casted her spell it instead grew out of control and transformed Ponyville into a Town for Nightmare Night.
Nightmare Night draws near, and as it does, strange things begin to happen around Ponyville. Scary strangers threaten the town, and things will change for the Cutie Mark Crusaders forever.
Luna issues a challenge to the foals of Ponyville. With the help of Discord’s magic, she turns Ponyville into a hunting ground of beasts, monsters, and foul creatures. Who is hunting who becomes unclear due to a determined group of friends.
