Description: The plot closely follows the events depicted in the original Japanese comic and its anime adaptation, with some minor modifications in certain instances.
By the year 2001, all prison institutions have been privatized. Ricky Ho (Fan Siu-wong), a martial artist and former music student, is sentenced to 10 years in prison for manslaughter after killing a crime lord who was indirectly responsible for the death of his girlfriend Anne (Gloria Yip). Flashback scenes reveal that a group of thugs had captured her after she had witnessed their heroin deal. Anne was so scared in captivity that she ran upstairs and then leapt off the roof to her death.
One morning in the prison bathroom, an elderly inmate named Omar is viciously beaten by the captain of the cells, Samuel. As Samuel leaves, Ricky trips him, and Samuel falls on a piece of wood with nails on it, hand and face first. As Samuel devises a plan to get back at Ricky, one of the inmates suggest that they should have Zorro, a dangerous, morbidly obese inmate, kill him. Omar is later informed by the guards that they turned down his probation after Samuel tells the guards that Omar was spreading rumors although this was untrue. Stricken by grief, Omar hangs himself.
The next day, Zorro attacks Ricky, but is quickly and horribly killed along with Samuel. Shortly after, a member of the fearsome Four Heavenly Kings (Gang of Four in the English dub) named Oscar, the leader of the North Cell, suggests that Ricky should see the sadistic one-eyed Assistant Warden Dan. After Ricky confronts Dan, he suggests Oscar to kill Ricky. Outside the prison yard, Oscar and Ricky engage in a fight, which ends with Ricky defeating and killing Oscar.
Later on, Ricky soon discovers that the Gang of Four is growing illegal opium for profit. Rogan, leader of the West Cell, discovers that Ricky had set the poppy garden on fire and they both fight. As the fight goes on, Brandon, leader of the South Cell, throws his needles and ties Riki-Oh up with them, leaving him defenseless. Meanwhile, the guards report to Dan that the Warden is returning from his vacation in Hawaii, prompting Dan to raise the Zero Alarm. While the fight continues, Tarzan, leader of the East Cell, interferes, claiming that he wants to fight Ricky. As the Zero Alarm goes off, Ricky and the Gang of Four part ways for now.
The next day, the Warden and his spoiled, overweight son return from their vacation. Dan informs the Warden about the incidents during his absence, including the poppy garden which infuriates the Warden. Dan escorts the Warden to Ricky’s cell. As the Warden questions him, Tarzan bursts through the wall and fights Ricky once again, which ends with Ricky brutally defeating Tarzan. The Warden then activates a ceiling trap to crush Ricky. As Ricky struggles to stay alive, Tarzan regains consciousness and saves him from being crushed by the ceiling, at the cost of Tarzan’s life.
Later, the Warden orders the inmates to bury Ricky alive, which they reluctantly obey. The Warden claims if Ricky survives by staying underground for a week, he will consider freeing him from prison. As the week quickly passes by, Ricky survives, but the Warden does not free him. Later that night, Ricky is chained in his cell. A fellow inmate, named Freddy, brings him food so Ricky can regain his power. However, another inmate sees this and informs Dan about it and in response, Dan mortally wounds Freddy. Dan, dragging Freddy’s body with his hook, then opens Ricky’s cell to show the body to him. However, Dan and the other inmate find that Ricky has broken free from the chains, and Ricky kills the inmate and knocks out Dan’s remaining eye. As the guards rush to the scene, the inmates rebel and violently ambush Dan.
In the kitchen, Ricky, the prisoners, and Dan burst through the wall and the Warden shoots Dan with a gas-pressured bullet, causing him to inflate and violently explode. Rogan and Brandon then confront Ricky one last time, which ends with Ricky gravely injuring Rogan. Brandon, realizing Ricky is far too powerful for him, flees from the scene, but not before the Warden shoots and kills Brandon. The Warden, revealing that he too, is a martial artist, transforms into a grotesque creature and battles Ricky. The fight quickly ends with Ricky crippling and throwing the mutated Warden into a meat grinder. In the finale, the prisoners rebel once again and start to attack the guards. Ricky then breaks the prison wall, allowing all the prisoners and himself to go free.
