Purnell stars as Rhiannon, “a quiet wallflower who develops a vengeful and intoxicatingly liberating taste for murder,” per the official description. Rhiannon is overlooked at work, her boyfriend won’t commit and her dad is sick, and eventually, she’s “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?”

The supporting cast includes Nicôle Lecky ( Sense8 ), Jon Pointing ( Starstruck ), Calam Lynch ( Bridgerton ), Leah Harvey ( Foundation ), Jeremy Swift ( Ted Lasso ) and Dustin Demri-Burns ( Slow Horses ). Kirstie Swain ( Run ) serves as writer and executive producer on the series, which is based on the novel by C.J. Skuse and will air on Sky Atlantic in the UK.
