Every generation, a portal opens up between the Outerworld and Earth. Emperor Shao-Kahn (Brian Thompson), ruler of the mythical Outerworld, pounces the moment the portal reopens and slips through with his mighty warriors, intent on total domination and uniting the two worlds. However, he has only seven days to complete his task. In the meantime, opposition grows and warriors Sonya Blade (Sandra Hess), Jax (Lynn “Red” Williams), Kitana (Talisa Soto) and Liu Kang (Robin Shou) get ready for war.
Obi-Wan Kenobi (Ewan McGregor) is a young apprentice Jedi knight under the tutelage of Qui-Gon Jinn (Liam Neeson); Anakin Skywalker (Jake Lloyd), who will later father Luke Skywalker and become known as Darth Vader, is just a 9-year-old boy. When the Trade Federation cuts off all routes to the planet Naboo, Qui-Gon and Obi-Wan are assigned to settle the matter.
