A huge storm has started. The clouds have darkened. The wind is howling. Jason, becoming quite scared and has found himself under the protection of his mother's arm on the couch. Wrapped up in a blanket he asks if the rain and lightening will get in the house. Playfully, Jason's mom encourages him to use his imagination to protect and save them.

Now in his knight's armour, Jason begins his journey through his imagination to battle the Water Monsters.

The Evil Rain King, Er'K, sees Jason getting stronger and summons the Water Dragon to keep him from reaching the castle to save his mom, who has been kidnapped by Er'K.

Now battling the Water Dragon, Jason must take shelter in a cave. Wandering the cave he stumbles upon a magical cape. With the cape tightly around his neck, Jason emerges from the cave to battle the Water Dragon once more. Realizing Jason has found the Cape of Legend, the dragon stops his battle with the young knight. Explains what the boy has found, who he really is and the two unlikely friends agree to help one another reach the castle to defeat Er'K.

Once they reach the castle the dragon is knocked out by a lightning bolt thrown by Er'K leaving Jason alone. Scared and feeling defeated himself, Er'K claims victory until the dragon wakes and reminds Jason that he has the Cape of Legend and to use his imagination and the cape to defeat Er'K.

Twirling the cape to move the clouds away to expose the sun, Jason defeats Er'K and saves the kingdom.

The Water Dragon then reveals himself, his true colour and his name, Dargon.

Jason saves his mom and finding themselves tightly snuggled back on the cound and ready for bed.

Until the next adventure.
