In April 2054, Washington, D.C. has a special police force called PreCrime that stops murderers before they act. Murders are predicted using three Precogs, mutated humans who "previsualize" crimes by receiving visions of the future. Over the past six years, PreCrime has successfully reduced the city's murder rate to zero, and the Federal government is on the verge of adopting it, even though the public finds it controversial. Captain John Anderton (Tom Cruise), the head of PreCrime, has been suffering from drug addiction since the unresolved disappearance of his son, Sean, which led to his wife, Lara (Kathryn Morris), divorcing him. With PreCrime poised to go nationwide, the system is being audited by Danny Witwer (Colin Farrell), an agent from the United States Department of Justice. In the middle of the audit, the Precogs generate a new prediction, one saying that Anderton will murder a man named Leo Crow in thirty-six hours. Anderton does not know Crow, but flees the area as Witwer begins a manhunt.

In 2084, Earthbound construction worker Douglas Quaid is having troubling dreams about Mars and a mysterious woman there. His wife Lori dismisses the dreams and discourages him from thinking about Mars, where the governor, Vilos Cohaagen, is fighting rebels while searching for a rumored alien artifact located in the mines. At "Rekall", a company that provides memory implants of vacations, Quaid opts for a memory trip to Mars as a secret agent fantasy. However, during the procedure, before the memory is implanted, something goes wrong, and the story diverges between the question of what is real and what is hallucination. Apparently, Quaid starts revealing previously suppressed memories of actually being a secret agent. The company sedates him, wipes his memory of the visit, and sends him home. On the way home, Quaid is attacked by his friend Harry and some construction coworkers; he is forced to kill them, revealing elite fighting-skills. He is then attacked in his apartment by Lori, who reveals that she was never his wife; their marriage was just a false memory implant and Cohaagen sent her as an agent to monitor Quaid. He is then attacked and pursued by armed thugs led by Richter, Lori's real husband and Cohaagen's operative.

The United States has lost the war on drugs. Substance D, a powerful and dangerous drug that causes bizarre hallucinations has swept the country.

The year is 2078. The planet Sirius 6B, once a thriving mining hub, has been reduced to a toxic wasteland by a civil war between the mining company, known as the New Economic Block (NEB), and the Alliance, a group of former mining and science personnel. Five years into the war, Alliance scientists created and deployed Autonomous Mobile Swords (AMS) — artificially intelligent self-replicating machines that hunt down and kill NEB soldiers on their own. They are nicknamed "screamers" because of a high-pitched noise they emit as they attack. Screamers track targets by their heartbeats, so Alliance soldiers wear "tabs" which broadcast a signal canceling out the wearer's heartbeat and rendering them "invisible" to the machines.
