In the action fantasy movie Mortal Kombat, warriors go head to head to try to save the world from the plans of evil forces. This 2021 film is the latest adaptation of a video game franchise that has been around for decades. In 17th-century Japan, Lin Kuei assassins led by Bi-Han attack and kill members of the rival Shirai Ryu ninja clan and Hanzo Hasashi's wife and son. Hanzo kills the attackers before being killed by Bi-Han and taken to the Netherrealm. Raiden, god of thunder, arrives and takes Hanzo's surviving infant daughter to safety. In the present, the realm of Outworld has defeated Earthrealm in nine of ten deathmatch tournaments called "Mortal Kombat", intending to conquer it. However, an ancient prophecy is uncovered, stating that the "blood of Hanzo Hasashi" will unite a new generation of Earthrealm's champions to prevent Outworld's victory. Aware of this, soul-eating sorcerer Shang Tsung employs warriors to kill Earthrealm's champions, identified by a distinctive dragon mark, before the next tournament begins.
