Ella Purnell is back as wallflower-turned-killer Rhiannon Lewis in a first look at Sweetpea season two.
Sky and STARZ dropped the still of the Fallout and Yellowjackets star in the darkly comic thriller on Tuesday, showing Purnell holding a ketchup bottle with the word “Monster” scrawled on the wall behind.
“Navigating a new promotion, an irresistible rebound, and a copycat killer threatening to expose her, the kill list is mounting,” reads a plot synopsis for the upcoming installment, coming in 2026. “And Rhiannon is forced to question whether her perfect ex, AJ, was right: Is she a monster?”
Rish Shah joins the cast as Rhiannon’s romantic interest Gabriel, alongside Tamsin Greig who stars as AJ’s mother, Liv. Taj Atwal (Riot Women, Line of Duty) steps in as Freya, Rhiannon’s formidable new boss at the Carnsham Gazette, while Jenny Walser (Heartstopper, Star City) plays an adoring new friend Daisy.
Returning to the series are Jon Pointing (Big Boys, Run Away), Jeremy Swift (Ted Lasso, Downton Abbey), Leah Harvey (Foundation, The Scurry), Ingrid Oliver (Thursday Murder Club, Doctor Who), Nitin Ganatra (Mr Bigstuff, Sexy Beast) and Alexandra Dowling (Emily, Game of Thrones).
Sweetpea is created by Kirstie Swain, based on the 2017 novel by CJ Skuse.
Season one, released in 2024, premiered to critical and fan acclaim. The Hollywood Reporter‘s review of Sweetpea said: “What makes the British series more unsettling and ultimately more compelling is its willingness to sit in the murky middle ground separating vengeance and cruelty, victim and perpetrator.”
Purnell is also known for her movie appearances, such as in Maleficent and Miss Peregrine’s Home for Peculiar Children.
