In a deviously twisted coming-of-‘rage’ story, Ella Purnell (Yellowjackets, Fallout) stars as Rhiannon: a quiet wallflower on a darkly comedic and intoxicating journey of self-discovery, with deadly consequences.

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. So far, so shit. 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?

Further casting alongside Purnell boasts an array of exciting British talent, including Nicôle Lecky (Mood, Sense8) as Julia, Jon Pointing (Big Boys, Smothered) as Craig, Calam Lynch (Bridgerton) as AJ, Leah Harvey (Foundation) as Marina. Also starring Jeremy Swift (Ted Lasso) as Norman and Dustin Demri-Burns (Slow Horses) as Jeff.
