Starz released the teaser today for the deviously twisted coming-of-age story Sweetpea, which will premiere this October. Ella Purnell stars as Rhiannon, a quiet wallflower who develops a vengeful and intoxicatingly liberating taste for murder.

Ella Purnell, who also serves as executive producer, said, “I truly cannot wait for the world to meet Sweetpea! I’ve loved exploring this incredibly complex character, as well as working alongside our dynamic cast and powerhouses Ella Jones, Kristie Swain, and Patrick Walters.”

The actress continued: “This has been one of the most fulfilling experiences of my career so far. At its core, the series is about a woman finally finding her voice, told through a uniquely dark and comedic lens. I hope audiences have as much fun going on Rhiannon Lewis’ wild, coming-of-rage journey as we did bringing it to life.”
