Detective Jay Swan (Aaron Pederson) takes on a grisly new case in the small coastal community of Gideon in Northern Western Australia, where the red sand meets the turquoise blue sea and people go for a fresh start or to bury their past. When the case unexpectedly becomes linked to an outback drug syndicate boss Jay has been chasing for years, he enters a world where deception is king. He also crosses paths with his former wife Mary (Tasma Walton), who moved to Gideon to rebuild her life and is seeing a retired cop, Simon (Callan Mulvey). When Jay begins investigating the murder, the body count rises as he uncovers more dark secrets the town is hiding. His local Indigenous police partner, Fran (Jada Alberts), searches for the truth of what happened to her best friend who disappeared years ago, and a Swedish archaeologist, Sandra (Sofia Helin), faces a moral dilemma when her unexpected discovery on a dig, jeopardises her quest to rewrite history, but could also solve a murder.
