The film begins with an unsettling scene where an unknown figure, only identifiable by his hands, is crafting a terrifying weapon: a glove equipped with deadly blades for fingers. Meanwhile, a young girl named Tina finds herself sprinting through dark and steamy alleyways, overwhelmed by fear. Without warning, the mysterious man lunges at her, brandishing his lethal glove. Tina wakes up with a start in her bed, realizing it was just a nightmare. When her mother rushes in, she discovers Tina’s nightgown is torn, closely resembling the gashes inflicted by the glove in her dream.
The next day at school, Tina meets her friends: her boyfriend Rod, her close companion Nancy, and Nancy's boyfriend, Glen. During their time together, Nancy and Tina realize they've both experienced the same terrifying dream, while Glen and Rod appear to be concealing their own nighttime horrors. That evening, Nancy and Glen choose to stay over at Tina's house since her mother is away. Rod later joins them, making a scene from outside that scares the group. As the night progresses and the friends try to find comfort, Tina and Rod sneak away to a private space, while Nancy and Glen remain awake, determined to support their friend.
As the night deepens, eerie occurrences start to unfold. The wall above Nancy's bed appears to distort, taking on a human form that she cannot see in her drowsiness. In the other room, Tina is stirred by a noise outside her window—a figure is haunting her from the back yard. Compelled, she steps outside to confront the stalker, drawn into an alley like a silent puppet. Encountering bizarre elements, including a goat, the notorious man with a fedora and the infamous glove reveals himself. He torments Tina with laughter and a sly whisper of her name, stretching his arms impossibly wide, blocking her escape. In a panic, Tina runs back but is thwarted by the man who rends his own fingers, revealing vibrant blood. As tension escalates, she finds herself dragged into a gruesome nightmare where reality and dream blur, culminating in her own death that leaves Rod shocked and scrambling.
When Nancy recounts the tragedy at the police station to her father, Lt. Donald Thompson, the belief in Rod's guilt looms. Despite the couple's troubled home dynamic, Nancy's intuition tells her Rod isn't responsible; she knows him too well. The following day, their paths intersect again when Nancy stumbles upon Rod. He insists on his innocence, but their moment is interrupted by law enforcement, leading to Rod’s arrest.
In class, exhaustion overtakes Nancy, and she experiences a disquieting vision of Tina, now a ghostly figure in a body bag. Unable to resist, she follows a terrifying trail that leads her deeper into the school. Just as she is about to confront her nightmare again, she wakes to find reality has taken a toll, leaving her with a scorch on her arm.
Desperate to analyze the shared terror, Nancy consults Glen about harnessing dreams. Compelled to break the association with their nightmare's power, Nancy must delve into her own strength. Despite recoiling at the prospect of sleeping, she nonetheless ventures into a hazy realm, only to find that her nightmares are indeed coming for her, where the line between fantasy and brutal reality begins to shred.
After a haunting encounter in the bathtub, where a darker force pulls her into an abyss, Nancy awakens in a panic, determined not to yield to sleep once more. In an attempt to learn more about their tormentor, she visits Rod in prison, confirming that he, too, is tormented by the figure chasing them both in dreams.
The tension escalates as Nancy and Glen scheme to unravel the mystery behind their nightmare. Yet, time is slipping, and horror strikes; Rod meets a fatal end, allegedly by hanging. Amidst growing distrust from her parents and confusion from the authorities, Nancy becomes increasingly frantic over the reality of their situation.
Driven by sheer determination, Nancy seeks answers from her mother, who finally reveals the dark past of Fred Krueger, a serial child murderer unjustly released and ultimately dealt with by Nancy's own parents. Realizing Freddy is attacking the children in their dreams seeking vengeance, the urgency grows.
As the body count rises, Nancy realizes she must confront this malicious ghost on her own terms. With conviction, she sets traps within her mind and in the physical realm, confronting Freddy in a battle for her life. The scenarios unfold in both realities, leading to fiery confrontations, emotional revelations, and the challenging of fears.
In the end, with everything hanging in the balance, Nancy comes face-to-face with Freddy one last time. Just when all hope seems lost, she taps into the essence of fear itself, reciting, > "You're nothing. You're shit." With newfound strength, she casts him into oblivion. As she awakens from her nightmarish world, the supposed safety of reality is shattered once more, reminding audiences that not all battles are easily won when nightmares awake and haunt the living.
