PART TWO: THE ROAD WARRIOR
He offers the refinery-people the chance to walk away free, if they leave the refinery, the tanker and all the fuel to him and his gang. He gives them one day to decide.
While Humungus is making his speech, the Feral Kid (Emil Minty) who gets in and out of the compound through tunnels, throws a razor-sharp boomerang at Humungus' gang, killing Wez's companion.
Wez goes berserk, and wants to storm the compound immediately, but Humungus wrestles him down, telling him to bide his time - he'll get his revenge once the fuel is theirs.
The people of the compound are divided; some want to accept Humungus' offer while Pappagallo and others, among them the Warrior Woman (Virginia Hey), try to dissuade them. As the discussion gets more heated, they forget about Max, who undoes his cuffs.
The Feral Kid crawls out of his burrow next to Max, who plays the musical box to entertain him and - when the kid laughs with delight - carelessly throws the toy to him.
The discussion isn't going Pappagallo's way. Most of the refinery people want to give up, a sticking point being that they have no vehicle that can pull the tanker, and that they're no match for Humungus' brutal gang anyway. Max offers to deliver a rig to haul the tanker, in return for his car and all the fuel he can carry. The deal is accepted.
In the dead of night, Max and the dog set off on foot, Max carrying fuel in jerrycans. Near Humungus' camp, he stumbles and the noise alerts the guards. But the Feral Kid, who's followed Max, draws them off by imitating the call of a wild animal.
In the morning, Max arrives at the hill where he left the Gyro Captain shackled to a log, only to find that that resourceful gentleman has set off across the wasteland, dragging the log.
Max follows his trail and catches up with him. They arrive at the gyrocopter, finding a dead man who'd been killed by the Captain's snake. Max checks the man for supplies, finding a shell for his sawed-off shotgun (which had empty chambers the entire time).
Max, dog and Gyro Captain fly to the truck where Max found the musical box. Max gets the truck started and throws the Gyro Captain the keys to the shackles, then drives off with his dog.
The Gyro Captain calls "We're partners!" after them. The gyrocopter follows in Max's wake as he heads off to break through the siege. Max takes Humungus' gang by surprise, and - aided by the Gyro Captain who drops snakes on the pursuers - makes it into the compound, although the truck suffers substantial damage. Humungus' gang are in hot pursuit, and Wez gets inside the compound by climbing aboard the truck.
The gang now attacks the gate to get inside. In the confusion, no one except Max notices that Pappagallo is wounded while defending the gate. Max runs to take his place, using a flame thrower to prevent the enemy from breaching the gate. Wez brutally kills one of the compound crew and escapes to the outside. The compound people now greet Max as a friend and hero, wanting him to drive the truck for the escape run.
Max just wants to get his fuel and go. The Gyro Captain lands in the compound, attracting excited attention. He immediately befriends a pretty young girl (Arkie Whiteley), persuading her to run away with him. That night, Humungus, furious with the turn of events, crucifies and tortures the remaining captives on a hill outside the compound, and threatens that none of them will get out alive.
While the compound is listening to his ranting, the Gyro Captain and the girl make for the 'copter, but at the last minute, the girl changes her mind - she won't leave her people. The Gyro Captain stays in the compound with her.
Meanwhile, Max is fueling up and getting ready to leave. Pappagallo tries to persuade him to drive the truck. Max refuses, and Pappagallo in his disappointment confronts him, calling him a coward, no better than the garbage outside.
When Pappagallo asks Max about his history, wanting to know how he became so heartless, Max hits him. Returning to his work, Max finds the Feral Kid has hidden himself in the Interceptor, obviously expecting to tag along.
Max evicts him without ceremony. As Max pulls out of the compound at daybreak, The Gyro Captain tells Max he's making a big mistake.
Humungus' gang sees Max driving away, and Wez - disobedient to his leader's will - sets off in pursuit with some companions. Max uses his booster tanks to escape, however, Wez does the same and overtakes Max.
