Sky and STARZ announced that filming has begun in London on the second season of the critically acclaimed, darkly comic Sky Original thriller Sweetpea. Ella Purnell returns as wallflower-turned-killer Rhiannon Lewis.

Rish Shah (Overcompensating, Joy) 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.

A synopsis for the new season reads: “Killer wallflower Rhiannon Lewis is back in season 2 of the iconically brazen and darkly comic thriller. Navigating a new promotion, an irresistible rebound, Marina still hot on her trail, her sister selling her family home and a copycat killer threatening to expose her, the kill list is mounting. But now that she’s harnessed her rage and found her power, Rhiannon is forced to question whether her perfect ex AJ, was right: is she a monster?”

“We are thrilled that ‘Sweetpea’ and the world of Carnsham are back in full swing for season two, with new and exciting characters for what promises to be an intoxicating ride for Rhiannon as she continues on her murderous journey,” executive producers Ella Purnell, Ella Jones and Patrick Walters said in a statement. “This season, the stakes are even higher, and as the consequences of her actions begin to close in, questions of morality and justice will come into play.”
