Here's Max's story in a nutshell - He lost his first child when Toecutter and his cronies killed him and Max went bonkers and took them all out.
Max wandered out into the wasteland after the world went to hell apparently forgetting his wife survived. He then had a daughter who was killed by some evil gang who were looking for gasoline and cigarettes. He killed the bad guys, saved the day, and went crazy.
Max wandered out into the wasteland again and was just minding his own business when the minions of Immortan Joe swarmed around him, wrecked the interceptor, and took Max prisoner, shaved him and gave him a haircut. He then escaped, killed Joe, saved the day, and rescued the hotties
Max wandered out into the wasteland again, found another car similar to his original interceptor, and was just minding his own business when the minions of the Ayatolla of Rock and Rolla swarmed around him and tried to take his ride. He then wound up at the refinery and teamed up with the gyro captain, saved the day, and rescued the little kid who grunted.
Max wandered out into the wasteland again, found another car and some camels, and then was swarmed upon by the pilot of an odd looking little airplane, the pilot looked a lot like the gyro captain except his teeth were much better. Max wound up in Bartertown, was exiled, and was saved by weird overly loud kids who gave him a haircut. Max battled the evil forces of Bartertown, saved the day, and then wandered out into the wasteland again...
