Princess Josian dreams of becoming a knight of Arundel Castle, while her best friend Jim Puttock dreams mostly about pies.
Life at the castle is peaceful and happy - until a dragon begins attacking nearby villages.
Determined to prove herself, Josian drags Jim on a quest to find a legendary giant who can save them... but Bevis isn't the hero they were expecting.
With rivals trying to steal the glory for themselves, Jim, Josian and Bevis must work together to stop the dragon and save Arundel.
After all, saving the day takes more than big muscles - it takes big hearts too.
