One night, the mother tells her son a bedtime story about a prince who climbs through a bush of thorns to bring Sleeping Beauty back to life. The next day, the boy recognizes the jagged swire on the wall as representative of his own bush, and he attempts to climb them in an attempt to duplicate what the prince did.
