MAD MAX (1979)
In a not-too-distant dystopian future, when man's most precious resource -- oil -- has been depleted and the world plunged into war, famine and financial chaos, the last vestiges of the law in Australia attempt to restrain a vicious biker gang. Max (Mel Gibson), an officer with the Main Force Patrol, launches a personal vendetta against the gang when his wife (Joanne Samuel) and son are hunted down and murdered, leaving him with nothing but the instincts for survival and retribution.

THE ROAD WARRIOR (1981)
After avenging the death of his wife and young son at the hands of a vicious gang leader, Max (Mel Gibson) drives the post-apocalyptic highways of the Australian outback, fending off attacks from nomadic tribes that prey on outsiders. Falling into an encampment led by the relatively peaceful Pappagallo (Mike Preston), Max at first schemes to steal their oil, but soon becomes the group's reluctant defender against the hulking Humungus (Kjell Nilsson) and his ruthless marauders.

MAD MAX BEYOND THUNDERDOME (1985)
In the third of the "Mad Max" movies, Max (Mel Gibson) drifts into an evil town ruled by Turner. There he becomes a gladiator and gets dumped in the desert where he is rescued by a band of feral orphans who have been looking for help for years. When several of them take his appearance as a sign and go off into the desert, he follows them back to the town.

MAD MAX FURY ROAD (2015) 
Haunted by his turbulent past, Mad Max believes the best way to survive is to wander alone. Nevertheless, he becomes swept up with a group fleeing across the Wasteland in a War Rig driven by an elite Imperator, Furiosa. They are escaping a Citadel tyrannized by the Immortan Joe, from whom something irreplaceable has been taken. Enraged, the Warlord marshals all his gangs and pursues the rebels ruthlessly in the high-octane Road War that follows.
