Netflix's Chilling Adventures of Sabrina is ending later this month after Season 4 drops December 31. This bummer news was announced over the summer, though via a new trailer we're starting to see what the beginning of the end looks like. Check it out below.

The final season will have eight episodes, and it will be kicking up the stakes as Sabrina Spellman (Kiernan Shipka) and her friends prepare to take on a new evil. In addition to Shipka (Mad Men), the show also stars Tati Gabrielle (who will also be in the upcoming Uncharted movie) and Miranda Otto (The Lord of the Rings). Of the show's cancelation, showrunner Roberto Aguirre-Sacasa (Big Love) said: "Working on Chilling Adventures of Sabrina has been an incredible honor from day one."

We have a big comprehensive guide to everything that's known (so far) about the Riverdale sister show's final season--including an overview of what went down in the first three seasons. The official synopsis accompanying the new trailer teases: "Sabrina's new normal quickly dissolves as menacing spirits set their sights on Greendale. In a battle of supernatural wits, who will be left standing?"
