Netflix’s Fear Street trilogy has transported viewers back to 1994 and 1978 in order to solve the mystery of the Shadyside Witch. Once known as Sarah Fier, the witch placed a curse on the town of Shadyside years and years ago, something the characters in the first two installments find out the hard way. Fear Street Part 3: 1666 will help fans understand why Sarah has a grudge against Shadyside in the first place, bringing them back to the past once more — this time, all the way to 1666.

[Spoiler alert: This article contains spoilers for Fear Street: 1994 and Fear Street: 1978.]

What is ‘Fear Street Part 3: 1666’ about?

The final moments of Fear Street Part 2: 1978 saw Deena (Kiana Madeira) attempting to end the curse of the Shadyside Witch by reuniting her severed hand with the rest of her bones. The result wasn’t quite what she expected. Instead of bringing the curse to a screeching halt, Deena finds herself pulled back in time — and seemingly placed into Sarah Fier’s body.

Fear Street Part 3: 1666 will see Deena learning what Sarah went through back in the 1600s. This will likely give her a better understanding of where the Shadyside curse came from — and how to end it.

The brief preview at the end of the second film shows Sarah involved in a witch hunt led by the people in her town. Knowing her grudge against Shadyside — and her nickname throughout the films — it’s not difficult to predict she’ll be the one they’re tracking down.

‘Fear Street Part 3: 1666’ arrives on Netflix this week

Fear Steet Part 3: 1666 has several storylines to wrap up and a number of mysteries to solve. Fortunately, fans of the first two films won’t need to wait too long to find out what happened to Sarah. The third and final installment will be available to stream on Netflix on Friday, July 16, 2021.

This release date falls in line with the other two, as each Fear Street film has been set a week apart. This gives viewers just enough time to process new developments before diving into the next chapter.

Is the third movie the final chapter in the series?

Is Netflix’s ‘Fear Street’ Trilogy Based on a Book?

Fear Street Part 3: 1666 wraps marks the final installment in Leigh Janiak’s slasher trilogy. The film will reveal the origins of the Shadyside Witch, and it will conclude the present-day story unfolding with Deena, Sam (Olivia Scott Welch), and Josh (Benjamin Flores, Jr.).

While the third film marks the final chapter in this story, however, it’s possible Netflix will continue to bring viewers horror stories within this universe. The trilogy is loosely based on R.L. Stine’s book series of the same name, and the novels cover a wide range of scenarios. While nothing is confirmed just yet, the streamer could decide to expand upon these stories.
