It's ten years since the 'Brig' girls saved the world from Emilino's evil plan. Busy adults now, they still meet when they can. We find the girls discussing the high number of tsunamis that seemed to be occurring. They each receive a postcard from an unknown source and the girls immediately question whether their old foe Emilino is at the root of what is going on. This means that our Brig girls will begin a quest to get to bottom of the issue. Will the girls be able to find out the cause and put and put an end to it? Read on intrepid adventure seekers.
