Before True/False we watched the Australian cult (Ozploitation) film Stone (1974) in movie club.
Someone's knocking off the members of the Grave Diggers Motorcycle Club and Stone must go deep undercover to find out who's responsible.
There are also posters out there that say "Before Mad Max there was Stone," which makes more sense. The Mad Max films were made after Stone and take place in the not-too-distant future. Who knows... Take the trip.
The Grave Diggers don't care.
