Described as a deviously twisted, coming-of-rage story, STARZ has just released the full trailer for their six-part series Sweetpea, ahead of its October 10th premiere. Ella Purnell, known for her standout performances in Yellowjackets and Fallout, stars as Rhiannon, a quiet wallflower who develops a vengeful and intoxicatingly liberating taste for murder.

Per the logline, “Rhiannon Lewis doesn’t make much of an impression – people walk past her in the street without a second glance. She’s continually overlooked for a promotion at work, the guy she likes won’t commit, and her dad is really, really sick. Then everything in her life turns upside down. Rhiannon is pushed over the edge and loses control. Suddenly the wallflower is gone, and in its place is a young woman capable of anything… Rhiannon’s life transforms as she steps into a new, intoxicating power, but can she keep her killer secret?”

Starring opposite Purnell are Nicôle Lecky as Julia, Jon Pointing as Craig, Calam Lynch as AJ, Leah Harvey as Marina, Jeremy Swift as Norman and Dustin Demri-Burns as Jeff. Purnell also serves as executive producer of the series.

Sweetpea is adapted from C.J. Skuse’s cult novel of the same name, with a screenplay by Kirstie Swain, Krissie Ducker, Laura Jayne Tunbridge and Selina Lim. Ella Jones directs and serves as executive producer.
