If the residents of Greendale — mortals and magic folk alike — don't band together right away, horrific and Lovecraftian entities known as "The Eldritch Terrors" will destroy the world as humanity knows it. And yes, tentacles are definitely involved because it just wouldn't be a proper Lovecraft-inspired story without some good ol' fashioned tentacles from beyond the veil of human comprehension. Each cosmic being goes by a different monicker: The Weird, The Returned, The Darkness, etc.
In an effort to prevent the arrival of "The Void" (aka the End of All Things) Sabrina Spellman (played by Kiernan Shipka) must travel to Hell and visit her evil double, Sabrina Morningstar (also played by Shipka). Based on this debut footage, it doesn't look like Morningstar gets a happy ending. "As the witches wage war, with the help of The Fright Club, Nick begins to slowly earn his way back into Sabrina’s heart, but will it be too late?" asks the official synopsis.

Based on the Archie Comics title of the same name, Chilling Adventures of Sabrina also stars Ross Lynch, Lucy Davis, Michelle Gomez, Jaz Sinclair, Tati Gabrielle, Adeline Rudolph, Richard Coyle, Miranda Otto, Lachlan Watson, and Gavin Leatherwood.
"Working on Chilling Adventures of Sabrina has been an incredible honor from day one," showrunner/executive producer Roberto Aguirre-Sacasa said when the series was canceled over the summer. "The cast, beginning with Kiernan as everyone’s favorite teen witch, has been an absolute joy. I am beyond thankful to the crew, writers, editors, assistants, and everyone for pouring so much love into this dark dream of a show."
Greg Berlanti, Sarah Schechter, Jon Goldwater, and Lee Toland Krieger also executive producer the series alongside Aguirre-Sacasa.
A fifth batch of episodes (entitled "Witch War") was planned to keep the story moving forward into next year, but had to be scrapped when Netflix decided not to renew the project. The final season (consisting of eight, one-hour episodes) hits Netflix on New Year's Eve (Thursday, December 31).
