In the summer of 1981, a young girl named Violet Hansen, played by Violet McGraw, embarks on a camping trip with her family in the scenic woods of Florida. During her wanderings, she stumbles upon a mysterious woman seated by a tranquil lake, who introduces herself as Rebecca Ferguson as Rose The Hat. Rose dazzles Violet with her magic tricks, creating an enchanting yet somewhat unsettling atmosphere. Violet soon notices the presence of several other eerie figures lurking nearby, watching their interactions with keen eyes. Rose hints to Violet that she possesses a special kind of magic in her, but as their encounter progresses, all the disguised watchers in the woods slowly close in on the innocent girl, hinting at darker intentions.
Meanwhile, in a different part of the country, Danny Torrance, portrayed by Roger Dale Floyd, is still haunted by traumatic memories from his time at the Overlook Hotel. His mother, Wendy, played by Alex Essoe, grows increasingly worried as Danny remains withdrawn, silent, and plagued by nightmares featuring spirits like the Grady Twins and the Woman in Room 237 — often called the Bathtub Lady. Using his unique psychic ability known as "the shine," Danny can perceive spirits such as Dick Hallorann, who shows him techniques to trap malevolent spirits within a mental box, offering him a faint hope for control and protection.
One evening, Danny and Wendy are watching television together when Danny excuses himself to the bathroom, only to encounter the Bathtub Lady waiting for him. Using his powers, Danny traps her inside his mental box, bringing him back to his reconciled state and restoring his voice to his mother. Years pass, and the story jumps to 2011, where an adult Danny, now played by Ewan McGregor, is living in New Jersey. He struggles with alcoholism, shown through brutal bar fights and reckless behavior. His strange encounters, including waking up next to a woman’s child one morning, highlight his inner turmoil and the lingering effects of his past.
At the same time, on Long Island, a teenage girl named Andi, played by Emily Alyn Lind, is contacted by an older man via a website. Rose The Hat, now played by Rebecca Ferguson, and her right-hand man Crow Daddy, depicted by Zahn McClarnon, observe her from afar. Andi exhibits her ability to manipulate others and, after leaving a distinctive snake-bite scar on a man she encounters, she is recruited by Rose into their cult called The True Knot. Rose affectionately nicknames her “Snakebite Andi,” promising her a life of pleasure and everlasting youth through their vampiric feeding on those with the shine.
In the town of Anniston, New Hampshire, a young girl named Abra Stone, with her parents Lucy and Dave, celebrates her fifth birthday. During the party, Abra impressively makes spoons float by simply saying “Abra Cadabra,” revealing her potent "shine." Meanwhile, Dan, the grown-up Danny Torrance, arrives in Frazier, New Hampshire, seeking a new start. He befriends a local named Billy Freeman, who learns about Dan’s troubled past and shares how Dan’s psychic gifts seem to connect to something beyond the ordinary. With Billy’s help, Dan begins working at a hospice, where he uses his abilities to comfort dying patients, earning the nickname “Doctor Sleep” from a dying man when Azzie, the hospice’s cat, accurately predicts death.
Over the next few years, Dan remains sober and continues his work, fostering a relationship with young Abra. Their bond deepens when Abra begins sensing the brutal murders carried out by the True Knot, who have been hunting for powerful shines to feast upon. The cult captures a talented young baseball player, Bradley Trevor, after tracking his games, and brutally murders him to consume his shine, which knowledge of his death causes Abra to scream in horror from her home. Abra’s telepathic connection leads her to locate Bradley’s body, and she begins to comprehend her own extraordinary powers and her importance in stopping the True Knot.
As Dan and Abra connect more deeply, they realize the True Knot's pursuit of her immense shine makes her a prime target. Rose, sensing her potential threat, attempts to invade Abra's mind while she sleeps—leaving her with injuries—confirming that she must eliminate her. Meanwhile, the cult's aging leader, Grampa Flick, begins to weaken and decay, drawing the remaining group closer to their desperate, final feed.
In a powerful turning point, Abra, with Dan’s guidance, tracks the cult's prey to a hidden location. They uncover Bradley Trevor’s buried body and, with Billy’s aid, approach the cult’s hideout. Together, they fight to protect Abra from the true evil, engaging in a fierce confrontation where Dan and Billy defend their friends against the murderous cult members, culminating in Crow’s death at their hands. Rose still poses a formidable threat, but Dan and Abra’s efforts force her into a confrontation at the ruins of the Overlook Hotel.
The former supernatural site becomes the battleground for the final showdown. Dan, haunted by his past and his trauma within the hotel’s sinister walls, navigates its decrepit halls, including Room 237, where he encounters a ghostly bartender resembling Jack Torrance. As his memories and fears resurface, Dan prepares for what will be his last stand. Rose The Hat arrives, and together, they clash amid the haunted spirits that dwell in the hotel. With Abra’s help, Dan manages to imprison Rose in the icy hedge maze outside, where she is wounded but still dangerous.
In the climax, Dan faces Rose inside the hotel, where she attempts to exploit his fears and absorb his shining. As their psychic battle reaches its peak, Dan unleashes the powerful spirits of the hotel—the Grady Twins, the Woman in the Bathtub, and others—against Rose, ultimately destroying her. However, in the process, Dan becomes possessed by the hotel’s malevolent spirits. With Abra’s intervention, he is able to send them into the boiler room, causing the hotel to burst into flames and banishing the spirits forever.
Sometime later, Abra continues to communicate with Dan’s spirit, solidifying their eternal bond. When her mother Lucy asks her about these conversations, Abra initially denies, but then admits she was talking to Dan, who remains a guardian figure in her life. She later prepares to face her future, confidently aware of the vast powers she possesses—powers that continue to guard her from the darkness, including the residual spirits of the Overlook, like the Bathtub Lady, waiting patiently for her in the shadows.
