In the remote cattle country of Western Australia's Kimberley, where seasonal flooding transforms the landscape into a vast inland sea, Special Investigator Odysseus "Odie" Kalaris is summoned when rising waters uncover human remains near Warrigal Creek Station.

What begins as the discovery of decades-old bones evolves into something far more sinister, revealing connections between historical water rights manipulation and powerful interests still operating today. When a station hand researching the same water dispute goes missing in suspiciously similar circumstances, Odie must navigate both rapidly rising floodwaters and the complex intersection of cultures that define this ancient land.

As Odie is cut off from outside support by the relentless monsoon, he uncovers links between the 1960s disappearance of boundary rider James Collins and the current station owner's desperate efforts to protect his family legacy. With floodwaters isolating the station and tensions rising among its inhabitants, each revelation tests Odie's tracking abilities and puts his understanding of both his mother's Gija heritage and his father's Greek traditions to the ultimate test.

The vast Kimberley landscape conceals secrets about water theft and murder, where justice has been denied for generations. But in a country where water always returns to its true path, some tracks lead to secrets that will kill to stay buried.

Odie must rely on traditional water knowledge and tracking skills to read the signs before the rising flood claims more victims, all while confronting a family dynasty built on stolen resources and concealed crimes.
