In 1666, a colonial town is gripped by a witch hunt that has deadly consequences for centuries to come, while teenagers in 1994 try to put an end to their town's curse before it is too late.
1666. An unspeakable evil has cast its unholy shadow over Union, the original settlement before its division into Sunnyvale and Shadyside, ushering in a new era of misfortune and terror. In the aftermath of the brutal mall killings in Fear Street: 1994 (2021), Deena finds herself plagued by vivid, blood-curdling visions of death and decay, forcing Cindy Berman, the only one who saw the sorceress and survived, after the bloody Camp Nightwing massacre in Fear Street: 1978 (2021), to step in. Now, there is no turning back, and until body and hand unite, no one is safe from the fiery curse of damned Sarah Fier. But evil has no boundaries. What will it take to rid Shadyside of the witch's sin?—Nick Riganas
1666After reuniting the severed hand of Sarah Fier with the rest of her corpse, Deena has a vision showing the events of 1666 from the perspective of Sarah Fier. She lives with her father George and brother Henry in Union, the original settlement before it was divided into Sunnyvale and Shadyside.
One night, Sarah and her friends Hannah Miller and Lizzie meet a reclusive widow to gather potent berries for a party, where Sarah stumbles on a book of black magic. The group arrives at the party and Sarah and Hannah are harassed by Caleb. The two run off and share an intimate moment, unknowingly seen by Mad Thomas. The next day, Pastor Cyrus Miller begins to act strange, as the town's food and water supply are poisoned. Sarah confides in Solomon Goode and wonders if she is responsible for the town's bad luck. The town then discovers that Pastor Miller has murdered twelve children in the chapel, including Henry and Constance. Sarah is attacked by Pastor Miller before he is killed by Solomon. That night, a town meeting is held at which the townspeople decide that witchcraft is the cause of the events, and Caleb claims that Sarah and Hannah are the witches responsible. Hannah is captured while Sarah escapes and the town declares that Hannah will be executed at dawn.
Sarah sneaks into the chapel where Hannah is confined and the two profess their love. Sarah decides to retrieve the widow's book and use it to make a deal with the devil and save Hannah, but she discovers that the book is gone and the widow murdered. She flees to Solomon's house and hides after he is ambushed by men hunting her. While hiding, she finds tunnels under his house, discovering a ritual as well as the widow's book. Solomon reveals he took the book to make a deal with the devil, offering Pastor Miller to be possessed in exchange for power and wealth. He offers to share it with her, and it is revealed that Solomon is in love with Sarah. Sarah rejects his offer and a fight ensues, Sarah's hand being cut off in the struggle. She escapes to the chapel only to be captured by Solomon and the townspeople. At her and Hannah's execution, Sarah convinces the town to spare Hannah's life by proclaiming she is the witch and swears vengeance to Solomon before she is hanged. Later, Lizzie, Issac, Hannah, and Abigail grieve Sarah and properly bury her body.
1994In 1994, Deena realizes that the Goode family is responsible for the Shadyside curse, as the firstborn of each generation repeats the ritual begun by their ancestor Solomon. Because of this, Sunnyvale has always prospered while Shadyside has become worse. Deena and Josh are found by Sheriff Nick Goode, but the two escape in Nick's car and arrive at Ziggy's house. The trio deduces they must kill Nick to end the Shadyside curse. After they recruit the help of Martin, the mall janitor, the group concocts a plan to lure Nick to the mall and set traps to have the Shadyside murderers kill him.
The group manages to trap the killers and Ziggy pours a bucket of Deena's blood over Nick, causing the killers to attack him. As Nick escapes into the tunnels, Deena and a possessed Sam follow him while the others fight off the killers. Sam attacks Deena, but she breaks Sam out of her possession temporarily before incapacitating her. Nick nearly kills Deena but she exposes him to the pile of beating organs in the tunnel, which gives him a vision of all of the killers' victims. Deena kills him, breaking the curse and reunites with Sam. The Goode family is later exposed for their actions, Josh meets his online friend in person, Ziggy reunites with Mrs. Lane, and Deena and Sam have a picnic date at Sarah Fier's grave.
In a mid-credits scene, an unknown person takes the widow's satanic book from the tunnels. (copied from Wikipedia)
