When the storm clouds gather, only the bravest answer the call.

Abbey and Dustin head to the Storm Wall to investigate a series of Barskall attacks. They arrive in the midst of a battle and discover an unlikely ally. They soon learn of a powerful weapon they can use to stop Dahlia and her seafaring pirates...

If they can find it in time.

The search will take them deep into enemy territory where their only hope for survival is the resourcefulness of their small but feisty crew.

As they race to find the weapon, a mysterious group of Storm Callers threatens to take over the seas and pave the wave for a whole new breed of Storm Raiders.
