Maxine Peake & Louise Stewart star in brand new feature I Swear

Funny, honest, and deeply human, I Swear tells the inspirational true story of John Davidson, a trailblazer whose honesty and humour helped the world better understand what it means to live with Tourette Syndrome.

Based on an inspirational true story, I Swear charts the remarkable journey of a Scottish man whose life was irrevocably changed by the sudden onset of Tourette’s syndrome. A bright, funny, football-mad lad with everything ahead of him, 15-year-old John Davidson’s life seemingly splinters in 1983 when he develops uncontrollable vocal and physical tics at a time when Tourette’s was barely understood, even by doctors. Feeling ostracized by the world around him — including his own family — he retreats into years of relative isolation, burdened by the anxiety, shame, and loneliness that can often accompany the neurological condition.

Everything shifts when John (now in his late twentiess) meets Dottie, the no-nonsense mother of a former schoolmate, who has recently been diagnosed with terminal cancer. The bond that forms between them is as unexpected as it is life-changing. With Dottie’s fierce encouragement and unwavering support, John finds belonging, purpose, and the confidence to be himself.

I Swear is released at cinemas nationwide on Friday 10th October
