Words were dangerous long before social media. A stranger than fiction true story of feuding neighbors, wicked letters and an absurd national scandal. Set in a 1920s English seaside town, the film follows deeply conservative local Edith Swan and rowdy Irish migrant Rose Gooding. When Edith and fellow residents begin to receive wicked letters full of unintentionally hilarious profanities, foul-mouthed 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 – begin to investigate the crime themselves, they suspect that something is amiss, and Rose may not be the culprit after all.
