Brace yourself for one of the year’s most atmospheric and unmissable thrillers.

Yellowstone’s Kelly Reilly stars alongside Happy Valley’s Rafe Spall in a haunting six-part crime drama created by Culprits writer-director Claire Oakley.

Set against the chaos of a once-in-a-generation storm, the series follows a detective-turned-schoolteacher whose shocking discovery drags her back into the shadows of her past — and straight into the path of her estranged police partner.

As the winds rise and power lines fall, long-buried secrets resurface, twisting loyalty, guilt, and redemption into a storm of their own.

Critics are calling it “intense, cinematic, and impossible to look away from.” This isn’t just another detective story — it’s a reckoning between truth, memory, and the ghosts we can’t outrun.
