Based on a stranger than fiction true story, Wicked Little Letters follows two neighbours: deeply conservative local Edith Swan (Olivia Colman) and rowdy Irish migrant Rose Gooding (Jessie Buckley). When Edith and fellow residents begin to receive wicked letters full of unintentionally hilarious profanities, foulmouthed Rose is charged with the crime. The anonymous letters prompt a national uproar, and a trial ensues.

However, as the town's women - led by Police Officer Gladys Moss (Anjana Vasan) - begin to investigate the crime themselves, they suspect that something is amiss, and Rose may not be the culprit after all.

It’s all brought together by director Thea Sharrock (Me Before You), who makes room for the darker narrative undertones of misogyny, hypocrisy, and repression while keeping the many twists of this story moving at the perfect clip for its comedy.
