If people think of Trudie Styler and her association with Italy, they are most likely to conjure up an image of the wine-making estate she owns with her husband, Sting, in Tuscany. Few people would know her as a woman raised on a council estate in the English Midlands who wandered through the labyrinthine, mafia-ridden backstreets of Naples for her latest documentary, Posso Entrare? An Ode to Naples, which draws on the lives of a host of city residents.

The documentary starts in the evocative Sanità district, where Styler meets Antonio Loffredo, a priest transforming the lives of young people who might otherwise have fallen prey to the Camorra mafia organisation, and where she visits multigenerational families living in case bassi – ground-floor homes that usually have just one room – and a door opening on to the street that provides the only source of air and light.
