chunk: While trying to escape a group of gang members – led by a crazed motorcycle rider named Wez (Vernon Wells) - Max manages to crash two of the gang member's vehicles and injure Wez; recognising his defeat, Wez flees. After collecting some fuel from the destroyed cars and checking a nearby Mack semi, Max inspects a nearby autogyro for fuel. Its pilot, the Gyro Captain (Bruce Spence), ambushes Max and manages to capture him briefly before being overpowered. In exchange for his own life, the pilot guides Max to a small oil refinery nearby. Max arrives to see the facility is under siege by a gang of marauders riding a motley collection of cars and motorbikes. The gang leader, known as "Lord Humungus" (Kjell Nilsson), tries to convince the refinery's defenders to surrender the facility in exchange for safe passage out of the area.
