A sleepover at the Crusader's clubhouse quickly becomes a life and death situation when Scootaloo is the only one who shows up at the clubhouse.

With nothing but a pocket-radio and a map she has to help her friends survive from a creature that's chasing them and guide them back to the safety of the farm.
