London's Southbank. A twenty something girl approaches a familiar part of London, where she asks a stranger to take her picture. She's not a tourist, her accent is a local one and her camera isn't your standard digital, complete with selfie stick. In an awkward exchange, the Polaroid picture is finally taken and the girl places the image in her collage book. We follow her with intrigue, as she takes more pictures of familiar sights around London, each one more curious then the next as we begin to grow concerned for her. Why is she taking photos with empty frames? And why today? And why in particular on The Queen's Walk, along the Southbank? Queen's Mile is a heartwarming story of a young woman's courage in coping with depression, in her own unique way.
