The American government has collapsed with the exception of the haven known as "Lost Vegas", ruled by King Elvis. The Red Army has been besieging Lost Vegas, but the lack of supplies over the years has relegated them to a gang of thugs. Forty years after the Soviet invasion, King Elvis dies and radio disc jockey Keith Mortimer announces a call for all musicians to come to Lost Vegas to try to become the new King of Rock 'n' Roll.
On July 4th, 2005, in a fictionalized United States alternate history reality, two towns in Texas: El Paso and Abilene were destroyed by twin nuclear attacks that triggered a catastrophe of unimaginable proportions, sending America into a state of anarchy and hysteria, as well as a Third World War (a fictionalized perspective of what the War on Terror would've escalated to). The PATRIOT Act has extended authority to a new agency known as US-IDent, which keeps constant surveillance on citizens—even to the extent of censoring the Internet and requiring fingerprints to access computers and bank accounts. In response to the recent fuel shortage in the wake of global warfare, the German company Treer designs a generator of inexhaustible energy, which is propelled by the perpetual motion of ocean currents, called "Fluid Karma". However, its inventor Baron von Westphalen and his associates are hiding the fact that the generators alter the ocean's currents and cause the Earth to slow its rotation, and that the transmission of Fluid Karma to portable receivers (via quantum entanglement) is ripping holes in the fabric of space and time.
In 1863, where an alternate nineteenth century Europe has made tremendous strides in steam-powered technologies, scientist Lloyd Steam and his son Edward have succeeded, after a lengthy expedition, in discovering a pure mineral water.

An experiment in Russian Alaska goes terribly wrong, with Edward being engulfed in freezing gases, but results in the creation of a strange spherical apparatus.

A power amplifier system issues orders for a final stand and for Koichi Todome, Midori Washio, and Soichiro Toribe to come to the central building. A Kerberos named Inui wanders through the halls of the Kerberos headquarters and then witnesses officer Koichi Todome boarding a helicopter. Angry, Inui feels betrayed by his master and asks why he's running away and not fighting until the end like he has ordered to his men. As the helicopter takes off, the army breach the headquarters.

His mother Sarah Connor had been preparing him throughout his childhood for his future role as the leader of the Human Resistance against Skynet, but was arrested after attempting to bomb a computer factory and imprisoned at a mental hospital under the supervision of Dr. Silberman. Skynet sends a new Terminator, designated as T-1000, back in time to kill John. The T-1000 is an advanced prototype composed of a mimetic polyalloy that allows it to take on the shape and appearance of almost anything it touches, and transform parts of its anatomy into knives and other stabbing weapons. The T-1000 arrives under a freeway, kills a policeman and assumes his identity. Meanwhile, the future John Connor has sent back a reprogrammed T-800 (Model 101) Terminator to protect his younger self.
