未来世界一个叫泰勒的矿工无意间发现了能开启不死的神秘之泉的钥匙，但却因此变得残暴而疯狂。在寻找神秘之泉的过程中泰勒和他的党羽们摧毁了性感而又嫉恶如仇的女战士朱莉的家乡，杀死了她的家人，于是一个复仇的故事开始了。。。

Upon discovery of a shard of the Loc-Nar (the evil orb from the 1st Heavy Metal), a miner named Tyler becomes posessed by an insatiable hunger for power & thirst for immortality. On his way to a planet which has a fountain of immortality, Tyler makes a pit stop at F.A.K.K.² (Federation-Assigned Ketogenic Killzone) because its inhabitants carry some immortality water in their bodies. Tyler abducts a few people and kills the rest, but misses one: Julie, the sole survivor enraged by Tyler's careless rampage, vows to avenge her family and kill Tyler before he reaches the fountain.
