In the early 1960s, Sandy (John Jarratt), Boo (Steve Bisley), Scollop (Mel Gibson) and Robbie (Phil Avalon) drive to the beaches north of Sydney for a surfing weekend. The boys are planning to give Sandy a memorable ‘one last fling’ before his impending marriage. Tension flares between university-educated Sandy and ocker Boo when Sandy decides not to join in the fun. At a local dance, Boo seduces Caroline (Debbie Forman), the teenage daughter of a caravan park owner (James Elliott) who discovers what has happened and comes looking for Boo with a gun.<ref name=aso />
