As a child in 1953,
Johnny Smith falls unconscious after a collision while ice-skating, then mumbles a prophetic warning to an adult who later suffers an accident. In an unconnected incident, a young, emotionally troubled door-to-door Bible salesman named Greg Stillson vindictively kicks a dog to death. By 1970, Johnny is a high school teacher in the small town of Cleaves Mills,
Maine, with a new girlfriend named Sarah. After winning repeatedly at a carnival
wheel of fortune, Johnny is involved in a car accident and falls into a coma. Waking up nearly five years later, Johnny finds that he has suffered a neural injury, with one part of his brain seriously damaged, making it a "dead zone". As if to compensate, other parts of the brain now show heightened activity. As a result, Johnny sometimes experiences clairvoyant visions when touching people and objects. His mother, who has become fanatically religious during the period of Johnny's coma, insists that he has been given a holy mission which he must not decline; she soon dies of a stroke. While in rehab at the hospital, Johnny helps various people, but is frustrated by sensational media coverage and the public's demands for assistance. When he rejects a lucrative offer to lend his name to fake predictions published in a tabloid, the tabloid editor denounces him as a fraud, but Johnny merely hopes that the public's disillusionment will let him resume a normal life. Johnny plans to resume teaching at the high school despite severe recurring headaches. Sarah visits him at his father's house, and they have sex for the first and only time. She makes it clear that she has a new life with her husband Walt and their child and leaves Johnny forever. Sheriff George Bannerman of
Castle Rock asks Johnny to help catch a local serial killer. After a nine-year-old girl is murdered, Johnny investigates and reluctantly identifies the Castle Rock Strangler as Bannerman's deputy Frank Dodd, who commits suicide after leaving a confession. As Johnny feared, the incident reignites the public's interest in his power and he is seen as too controversial to return to teaching. Greg Stillson, now a successful businessman and mayor of Ridgeway,
New Hampshire, enlists a
biker gang and threatens to kill the people he bullies if they reveal his actions or do not aid him. In 1976, he wins a seat in the
U.S. House of Representatives as an independent, having blackmailed a local businessman into raising funds for him. Johnny becomes a private tutor to a teenage boy in Ridgeway and develops an interest in politics. He meets Stillson, and is horrified to see a vision of an older Stillson, now
President, causing a worldwide nuclear conflict. As Johnny's health worsens, he contemplates Stillson's presidency, comparing his dilemma to someone with the ability to
time travel having the opportunity to kill
Hitler in 1932. Rather than assassinate Stillson to ensure the vision does not come true, Johnny procrastinates because of doubt in his vision, his abhorrence of murder, and his belief that there is no urgent need to act immediately since he has met an
FBI agent investigating Stillson as a possible threat. The FBI agent is killed by a car bomb. Meanwhile, Johnny's warnings that a disaster will occur at his pupil's graduation party are ignored by some, leading to several deaths. Now believing he must take more decisive action to prevent nuclear war, and learning his headaches are the result of a
brain tumor, Johnny buys a rifle to kill Stillson. At the next rally, Stillson begins his speech and Johnny shoots from a balcony. He misses and is wounded by guards. Stillson grabs a young child and uses him as a
human shield. A bystander photographs Stillson's act. Unable to shoot a child, Johnny is shot twice by the bodyguards and he falls from the balcony, mortally wounded. Dying, Johnny touches Stillson a final time. He feels only dwindling impressions and knows the terrible future has been prevented. When published, the picture of Stillson using a child as a shield ends his political career. An epilogue intersperses excerpts of letters from Johnny to his loved ones, a "Q & A" transcript of a purported
Senate committee (chaired by real-life Maine Senator
William Cohen) investigation of Johnny's attempt to assassinate Stillson, and a narrative of Sarah's visit to Johnny's grave. Sarah feels a brief moment of psychic contact with Johnny's spirit and, comforted, drives away. == Reception ==
