In Japan, Shirai Ryu grand-master Hanzo Hasashi (Patrick Seitz) and his young son Satoshi (Grey Griffin) are ambushed on their way home by several ninjas from the rival Lin Kuei clan. Hasashi kills them all after discovering that the Lin Kuei have slaughtered the rest of the Shirai Ryu, including his wife Harumi. The Lin Kuei's Grandmaster Sub-Zero (Steve Blum) appears, uses his freezing abilities to restrain Hanzo in ice, and then murders Satoshi. He then impales Hanzo through the neck with an icicle, killing him. Deep below in the depths of the Netherrealm (lorded over by master Shinnok), Hasashi is mysteriously resurrected and meets with the sorcerer Quan Chi (Darin De Paul), who persuades Hanzo to fight for him in the Mortal Kombat tournament so that he can exact his revenge on Sub-Zero (who is slated to attend the tournament). In addition Quan Chi asks Hanzo to bring back a key hidden at the temple of Shang Tsung, which will release Shinnok from his prison. Once Shinnok is released, he can return Hanzo and his family back to Earthrealm. Hanzo agrees, dubbing himself Scorpion.

Meanwhile, the thunder god Raiden (Dave B. Mitchell) and the Shaolin monk Liu Kang (Jordan Rodrigues) make preparations to defend Earthrealm by participating in the Mortal Kombat tournament, hosted by the aging warlock Shang Tsung (Artt Butler) (Emissary of Shao Kahn, the emperor of the Outworld. Shao Kahn has won 9 tournaments against Earthrealm. If he wins 1 more, as per the rules, Outworld can merge with Earthrealm and rule it as they see fit). The tournament's victor will battle Goro (Kevin Michael Richardson) to decide the fate of Earthrealm. The Netherrealm is led by Shao Kahn and if he wins, Earth as we know it will cease to exist. The pair are accompanied by out-of-work Hollywood actor Johnny Cage (Joel McHale) and Special Forces agent Sonya Blade (Jennifer Carpenter), with both having their own reasons for participating: Sonya is in pursuit of Black Dragon crime syndicate leader Kano (Robin Atkin Downes), and Cage believes that he is participating in a film project. Both were "selected" by Raiden to participate on behalf of Earthrealm.

Upon arrival on Shang Tsung's island, Scorpion attempts to steal Shinnok's amulet (the key to Shinnok's prison) from Shang Tsung on Quan Chi's orders, but Raiden persuades him not to follow through on the deal (Raiden tells Scorpion that Quan Chi is not a man to be trusted). Meanwhile, Cage, Sonya and Liu Kang witness Sonya's partner Jackson "Jax" Briggs (Ike Amadi) (who was brought to the Island forcibly by Kano) having his arms ripped off by Goro until Raiden intervenes, and cauterizes Jax's arms. During the course of the tournament, Cage barely claims victory over a Tarkatan, before realizing he is in an actual tournament, and not an action film.

Sonya successfully garrotes Reptile, and Kang fights Kitana, emerging as the winner when she yields. In an attempt to stop the Earthrealm heroes, Kano has his Black Dragon assassins infiltrate the island to kill them, but they are all killed by Scorpion. Kang, Sonya and Cage hook up with Scorpion on the Island. While attempting to fight Kano, Sub-Zero appears and helps deal with the assassins, but a vengeful Scorpion attacks him and tackles him off a bridge into a spike pit, impaling them both and killing Sub-Zero. Cage and Sonya pursue Kano in order to rescue Jax while Kang rushes to Shang Tsung's throne room to face Goro.

Quan Chi appears before the injured and impaled Scorpion and reveals that he was directly responsible for the slaughter of the Shirai Ryu, having disguised himself as Sub-Zero and manipulated the Lin Kuei into doing his bidding and that the real Sub-Zero had no part in the massacre. Enraged, Scorpion removes himself from the spike to exact revenge. At the climax of the tournament, Shang Tsung is revealed to have already known of Quan Chi's true intentions from the beginning and captures him. Liu Kang is almost killed during his match with Goro but is saved when Scorpion kills Goro with his Kunai, while Cage, Sonya and Jax successfully kill Kano.

Shang Tsung attempts to have Scorpion fight Kang, but the specter outsmarts the sorcerer and Scorpion attacks Shang Tsung instead, forcing him to give him the amulet, and willingly forfeits his status as a fighter, securing Kang's position as the victor of the tournament. Tsung warns that Shao Kahn will have his revenge and retreats to Outworld, and the island begins to collapse, with the Earthrealm heroes evacuating to a nearby boat, while Scorpion succeeds in killing Quan Chi in combat before joining his family and clan in the afterlife. Later on, in the boat, Raiden then tells Liu Kang that it was not his destiny to defeat Goro but to defeat Demon Torturer, Shao Kahn (Fred Tatasciore) himself.

In the aftermath, Shang Tsung is tortured by Shao Kahn for his failure before being ordered to make preparations for the invasion of Earthrealm.
