The strongest of the three Precogs that predict future murders.
In the year 2054, Agatha is a psychic that the United States government uses to predict and interdict murders within a 200 mile radius of the Washington, D.C. metropolitan area. She is the daughter of a woman addicted to a new designer drug that gives fetuses super powers. Since birth, Agatha shows a tendency towards precognition and mind reading. She knows a dark secret about her mother that could destroy the Pre-Crime program of which she is an integral part. Some people revere Agatha as a god or spiritual figure due to her powers. She is bald most of the time. Being bald enhances psychic powers. Also, floating a pool of milk while wearing a leotard enhances psychic powers. It is science... that is in books... legitimate books written by scientists.
After her mother is arrested for drug possession, Agatha becomes a ward of the Federal government. Her enlarged pre-frontal lobe affords her mental powers. She lashes out due to her lack of control of these powers. Agatha and a group of other psychic children are trained by Dr. Iris Henimen. Henimen and Lamar Burgess keep the three most powerful children in a state of sedation while their powers develop. When the three psychics turn 18, Lamar Burgess proposes the Pre-Crime program. Agatha and the others are to be used to predict murders in Washington, D.C., and a group of elite agents arrest the attempted murderers. The program is tested and works perfectly --except one case.
Lamar Burgess murders Agatha's mother Anne Lively because Anne Lively wants her daughter returned to her. Her time in a government drug treatment facility leaves Anne Lively a responsible person. Burgess lures Lively out to the forest and murders her in a way that circumvents Pre-Crime. Agatha predicts the murder of her mother, but Burgess tricks the elite agents. Agatha keeps this information secret until she has a chance to tell someone who can make a difference. She identifies Chief John Anderton of Pre-Crime as the man who can help using her future vision.
For six months, Agatha and the others successfully predict and prevent crime in Washington, D.C. until Department of Justice oversight agent Danny Witwer arrives. Witwer throws a wrench into the system. This distraction allows Agatha to warn John Anderton about Lamar Burgess. However, Burgess notices this warning and frames John Anderton for the future murder of a stranger known as Leo Crow. Anderton is force to go on the run.
However, Anderton returns for Agatha, searching for a Minority Report. Anderton takes Agatha to a local mall where a holographic pleasure center has the ability to access memories. Agatha is placed in the memory downloader as she remembers the murder of her mother. Anderton is kind of slow-witted and does not understand. He wants his non-existent Minority Report. Agatha tells him he does not have one. Anderton then takes Agatha to witness his murder of Leo Crow. He does not murder Crow, but Anderton discovers that the entire situation was a set up. Anderton flees with Agatha to his ex-wife's house.
At Anderton's ex-wife's house, Agatha just tells Anderton directly that Lamar Burgess murdered her mother because even with all the clues he never would have figured it out. Anderton is still confused. Agatha tells him to run as Pre-Crime agents are coming for him. Anderton is still confused. Pre-Crime agents arrest Anderton, retrieve Agatha, and place her back in her psychic meditation tank.
Anderton eventually escapes, reveals Burgess is a murderer, and shuts down Pre-Crime. Agatha and her psychic compatriots are released, give a massive government stipend and a house in a rural area, and left to live their life in quiet and solitude, away from the noisy murderers of Washington, D.C.
Agatha is in a near catatonic state most of the time. The drugs that her handlers inject her with as well as her meditation pool keep her in a state of trance. In this situation, Agatha's sole concern is preventing murder. If anything, Agatha wishes to prevent murder to stop the pain that she felt when her mother was murdered by Lamar Burgess. Her restricted upbringing makes Agatha extremely pliable to commands from authority figures like John Anderton. She has an affinity for people in pain or grief, offering advice and a kind word to those she encounters. She can also read minds which helps in evading people and confusing others.
