It is the late 1940s and Broome, a small pearling town in the heart of an ancient land, is still recovering from WWII. Ubby, a smart, street-wise Aboriginal girl, is the leader of a small rag-tag gang known as the 'Underdogs'. Trying to make a name for the Underdogs, she meets Sai Fong, a Chinese girl just off the boat from Shanghai. From the moment Ubby and Sai Fong meet, their worlds collide as they find themselves thrown into a series of bizarre adventures full of myths and legends and everything from ancient mechanical demons to fantastic beasts - and secrets never before exposed.
