The Annual Dessert Contest is around the corner and this year, Ylva decides to make her special Myrthus Cake to retain the trophy in Flake. But Baltak, spying on her, gives the same idea to Morag, his wife. The only problem is that Myrthus is hard to find and only grows on one island south of Flake. A race starts between Halvar and Baltak to get to the Myrthus first, and only Vic will be able to prevent traps and cheats along the way.
