A respectful nod to classic kids-in-peril adventure films that finds a group of reluctant kids stranded overnight in an abandoned jail. Their chaperon is missing, their cellphone service is non existent, and their patience with each other is running thin. Oh, and a big, hairy creature is trying to eat them. Hey... it's tough being a kid in a monster movie.

A ransom scheme turns into a nightmare for a group of kidnappers who become victims of a horrifying secret that must be paid every spring.
