When four backpackers vanish on Dunk Island in the wet tropics of North Queensland, Detective Bec Whitfield is thrust into a chilling search mission. The island's natural beauty masks a dark reality, and as the days pass, the hunt grows desperate. Two bodies are discovered, but the others remain missing, and suspicions of foul play rise. As Bec digs deeper, she uncovers a disturbing connection - each of the missing women had a relationship with a well-known resident of the small town. With the community in turmoil, the man becomes the target of relentless social media persecution; his reputation is dragged through the mud as rumours swirl about his involvement in the disappearances. The investigation grows increasingly complicated as Bec uncovers conflicting stories, personal motives, and dangerous secrets that threaten to tear apart the tight-knit coastal community.
