Letterbox is the story of Imani, a second generation Muslim girl from Bradford, who lives for her music. When her mother finds her and her brothers ticket’s to Glastonbury Festival, she rips them up, saying the only way she would be going to Glastonbury is in a Burka. So that's exactly what the feisty and determined Imani does. In an act of rebellion against her mother and a conscious provoking of the culture she so badly wants to fit in to, she dons her mum's ill fitting niqab and hitch hikes her way to her very own music heaven, forcing the cultural rubber of her young British Pakistani life to meet the road. This is a road movie played out in the most enchanting of playgrounds. Imani's eye opening adventure brings her fun, eccentricity, music from the soul, and friendships that cross stereotypes and break social barriers.
