Determined to give the Insomniac's a night of good dreams, Izzie and friends bring them to the Candy Realm; but nowhere is safe from Nightmare King.

The Dream Chasers arrive at Castle Nocturnia hoping to find the key to defeating the Nightmare King, but the castle won't reveal its secrets easily.

The Dream Chasers rush to crack the code to reveal Lunia's secrets while the Nightmare King presses a full-scale assault on Castle Nocturnia.
