A young hiker, Y/N gets lost and accidentally falls into a pit while stumbling in the dark. She wakes up to find herself in a whole new world that was never spoken of before except in children's stories. That's when she stumbles upon Barb (aka Mutt) and makes her first friend in the underground! But other monsters that live here aren't so welcoming.…
