The Quest

At an isolated pond in the wilderness of Victoria, Australia, a lone man fishing in a rowboat is surprised when the wind picks up, spinning an old farm windmill, and water violently churns in the middle of the pond. Young American orphan Cody Walpole finishes building his latest idea, a rail bike, which leads him to an abandoned campsite where he discovers a mysterious body. With the help of a construction manager and an Aboriginal musician, Cody embarks on a quest to uncover the truth about a legendary creature known as Donkegin, said to inhabit a sacred site in the area. He eventually builds a homemade cannon and a diving helmet to investigate the depths, facing treacherous challenges and unexpected twists along the way.
