James, Tristan, and Talia Jenkins receive a magical orb that glows, showing them a tiny dragon struggling to survive a storm at sea. The dragon, a special peace gift for King Arthur, will die before getting to the king without their help!

The orb holds all the secrets. Taking the leap and traveling back to the past to Medieval England, the children pledge their lives to help him.

From escaping the clutches of King Kong-size spiders to nearly drowning in a hidden maze, the dragon and kids encounter one hair-raising, brain-busting challenge after another.

Can the children help the dragon reach King Arthur in time for the peace summit?
