Sydney homicide detective Sergeant Scobie Malone and his offsider investigate the murder of Helga, whose corpse is found in the basement of the Sydney Opera House.

This anthology film brings together three stories—"Michael", "Judy", and "Toula"—each centered on a young Australian confronting personal and social choices about their future. Produced by the Commonwealth Film Unit, the film explores themes of identity, independence, and cultural tension through distinct perspectives from directors Brian Hannant, Oliver Howes, and Peter Weir.

Michael, a young man living within a conventional middle-class environment, begins to question his future as he encounters a group aligned with the countercultural movements of the late 1960s. As he is exposed to new ideas and ways of living, he is forced to reconsider the direction of his life. (Note: This film is one segment of the anthology feature "Three to Go" (1971).)
