Barrenjoey Road 01 | Saturday night on Barrenjoey Road

A heart breaking search for the hitch-hike girl. For a free-spirited teenager, growing up on Sydney’s northern beaches in the '70s was as good as it gets. Endless perfect surf breaks, days spent lounging on the beach with mates, parties every weekend. 18-year-old Trudie Adams was typical, hanging out with her girlfriends and looking forward to a trip to Bali.

On a Saturday night out at the Newport Surf Club in June 1978, Trudie’s boyfriend watches her leave to hitch hike home. She never makes it.

The laidback community quickly realise something is wrong. The popular teenager had no reason to go missing. Suddenly, the northern beaches don’t feel so safe anymore.

Trudie’s disappearance exposes the dark underbelly of the "insular peninsula". There are drugs, crimes against women and, potentially, police corruption.

Join investigative journalist Ruby Jones as she begins to unravel what happened to Trudie Adams.
