Mark Hartley's documentary explores a little-known period in Australian cinematic history, often overlooked in the cannon of `important works'. Throughout the 1970s and 1980s, innovative film-makers took advantage of relaxed censorship laws and pushed the boundaries of taste and decency to produce features including Snapshot and The Man from Hong Kong, which laid the foundations for future successes including Wolf Creek and Long Weekend.

As Australian cinema broke through to international audiences in the 1970s through respected art house films like Peter Weir's "Picnic At Hanging Rock," a new underground of low-budget exploitation filmmakers were turning out considerably less highbrow fare. Documentary filmmaker Mark Hartley explores this unbridled era of sex and violence, complete with clips from some of the scene's most outrageous flicks and interviews with the renegade filmmakers themselves.
