In the fall of 1986, five women disappeared from Perth, Australia within just five weeks. With no clear connection between them, police struggled to understand what was happening—until a 17-year-old girl escaped from captivity and led investigators straight to a suburban home hiding unimaginable crimes. 

This is the story of Mary Neilson, Susannah Candy, Noelene Patterson Parr, Denise Keren Brown and Kate Moir.
