is a 2000 Japanese zombie action film directed and co-written by Ryuhei Kitamura. The film was an independent co–production between Kitamura's company Napalm Films and Wevco Production in association with KSS and Suplex. In the film, a nameless prisoner, a nameless female and her Yakuza abductors fend off zombies in a forest that resurrects the dead while the Yakuza's mysterious leader attempts to open a supernatural gate hidden within the forest and seize its dark power.
The film was originally intended as a sequel to Kitamura's short film Down to Hell but was re-developed as a new film. Principal photography was originally intended to last 3 weeks but was extended to 7 months due to weather and financial issues.

Versus premiered at the Tokyo International Fantastic Film Festival on October 29, 2000. In 2004, an expanded edition titled Ultimate Versus was released that featured 10 minutes of new footage and improved music, effects, titles, and edits.

Plot
There are 666 portals on Earth that connect it to the other side. Lured by the prospect of gaining the power of darkness, many seek to find and open the portals. Somewhere in Japan, there exists the 444th portal known as The Forest of Resurrection.

In 10th century Japan, a lone samurai fends off a horde of zombie-like samurai creatures. Though successfully vanquishing the zombies, the samurai is confronted by a mysterious priest and his league of warriors. In an attempt to take out the mysterious priest, the lone samurai charges but is easily killed. Before dying, the lone samurai spots an ally behind him, who arrives too late to save him.
In present-day Japan, two prisoners escape through a forest and meet up with a gang of Yakuzas. When Prisoner KSC2-303 (Tak Sakaguchi) sees a girl (Chieko Misaka) that the gang kidnapped, he immediately becomes suspicious of what they plan to do with her. After a heated argument, KSC2-303 kills one of the Yakuza members, who resurrects as a zombie. During the chaos, KSC2-303 escapes back into the forest with The Girl. Disobey their orders to wait, the Yakuza pursue Prisoner KSC2-303 and The Girl.
KSC2-303 and The Girl come across a man crucified upon a tree. KSC2-303 steals the dead man's clothes and is confronted by one of the Yakuza. They engage in hand-to-hand combat while the other Yakuza begin facing problems of their own. The corpses of all the men they have killed and buried in the forest resurrect and attack them. KSC2-303 and the other Yakuza reluctantly cooperate to battle the zombies.
With the horde of zombies growing, the Yakuza call upon three assassins to aid them. The Yakuza leader, The Man (Hideo Sakaki), finally arrives and confronts them, angry that they lost KSC2-303 and The Girl. The Yakuza and Assassins take the upper hand and kill him first. But The Man easily jumps back to his feet and turns the Assassins and Yakuza into his own minions. Two of the Assassins escape and find KSC2-303. One is defeated by The Girl with a log, and the other is confronted by The Man and killed.
KSC2-303 attempts to force The Girl to tell him what is going on, believing that she has been hiding secrets from him the whole time. Before explaining thoroughly, The Man finds Prisoner KSC2-303 and The Girl. The Man begins explaining to Prisoner KSC2-303 that they are reincarnations of past lives. The Man plans to use The Girl as a sacrifice to open the portal hidden in The Forest of Resurrection and obtain the power of darkness. Unable to accept his explanations, Prisoner KSC2-303 attempts to kill The Man but is killed himself instead.
The Girl manages to reach Prisoner KSC2-303's body and feeds him a part of her blood before being taken by The Man's minions. During his unconscious state, Prisoner KSC2-303 experiences a flashback of his past life in the 10th century; he is the ally who was too late to save the lone samurai. He and The Girl (who is revealed to be a princess) are confronted by the mysterious priest (who turns out to be The Man) and his gang. Outnumbered and facing long odds, Pre-Prisoner KSC2-303 reluctantly kills The Girl to stop The Man from obtaining the power of darkness. Enraged, The Man viciously kills Pre-Prisoner KSC2-303. Prisoner KSC2-303 is awakened in the present with the truth fully revealed to him.
The following morning, Prisoner KSC2-303 confronts The Man and his minions for a final showdown. Prisoner KSC2-303 takes on the minions first and wins, leaving only The Man left. Prisoner KSC2-303 decapitates The Man and rescues The Girl, and both make their escape from The Forest of Resurrection.
