Fans of psychological horror, mark your calendars! Netflix is set to unleash Something Very Bad Is Going to Happen, a new eight-episode miniseries executive produced by Stranger Things creators Matt and Ross Duffer. All episodes of the highly anticipated series will drop simultaneously on Thursday, March 26, 2026, offering a chilling binge-watch experience.

The miniseries, created and showrun by Haley Z. Boston, delves into the unsettling week leading up to a wedding. Camila Morrone (Daisy Jones & The Six) stars as Rachel Harkin, the bride, while Adam DiMarco (The White Lotus) plays her fiancé, Nicky Cunningham. The couple travels to Nicky's wealthy family's secluded vacation home for what promises to be an intimate ceremony, but unsettling events quickly begin to unfold.

Described as an atmospheric horror, the series aims to explore the deep-seated fears around marriage through a horror lens, drawing inspiration from classic psychological thrillers like Carrie and Rosemary's Baby. Rounding out the cast are notable talents including Jennifer Jason Leigh as Nicky's mother, Victoria Cunningham, and Ted Levine, with Weronika Tofilska, Axelle Carolyn, and Lisa Brühlmann directing episodes. Produced under the Duffer Brothers' Upside Down Pictures banner, Something Very Bad Is Going to Happen promises to deliver a fresh wave of dread to Netflix subscribers worldwide.
