19-year-old Belinda Peisley vanished after she left a Blue Mountains hospital, west of Sydney, on the night of September 26, 1998.

The single mum-of-two disappeared within a year of inheriting a significant sum of money from a distant relative and buying a house in Katoomba, a small town in the Mountains.

Six persons of interest were named in Belinda’s case. By piecing together the stories and evidence surrounding these six, Last Seen Katoomba, uncovers a dark underbelly of drugs and violence and a culture of fear and intimidation that still exists in this town. Twenty years on, some are still too scared to speak about Belinda’s case.

The first episode of Unravel Season 3 lands on February 5.
