Everyone in Woodland is very tired of the winter and they fear that spring may never arrive. Franklin is particularly excited about the arrival of spring because that is also when his new baby brother or sister will be born. However Franklin becomes concerned that his mum and dad might not have time for him any more and anxious that he will not be a good brother.
In an attempt to prove himself worthy, (and get mum and dad's attention) he decides that he must bring spring to Woodland. Following the lead of a myth his mum has told him, he assumes the role of a knight and sets out of the woods on a quest for spring. With squire snail at his side he encounters some wild adventures and some very unusual characters.
