Movie plot title: Southland Tales Movie plot: On July 4, 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 version of what the nation may have become under the War on Terror). The PATRIOT Act has extended authority to a new agency known as US-IDent, which keeps constant surveillance on citizenseven 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 near-future 2008, Los Angeles (referred to as "The Southlands" by locals) is a city on the brink of chaos overshadowed by the growth of the underground neo-Marxist organization. The film follows the criss-crossed destinies of Boxer Santaros (Dwayne Johnson), an action film actor stricken with amnesia; Krysta Now (Sarah Michelle Gellar), a psychic ex-porn star in the midst of creating a reality TV show; and twin brothers Roland and Ronald Taverner (both Seann William Scott), whose destinies become intertwined with that of all mankind. The Taverner twins are revealed to be the same person by the engineers of Treer, duplicated when Roland traveled through a rift in space-time, while Boxer has become the most wanted man in the world despite his political ties and his having the fate of the future, in the form of a prophetic screenplay foretelling the end of the world, in his hands.
