Critically-acclaimed filmmaker Marc Isaacs paints a rich portrait of multicultural life in the UK by looking at the lives of immigrants living along the A5, one of Britain's longest and oldest roads. Stretching from London to the Welsh coast, the road has always been an important lifeline for new émigrés. Today, it is a microcosm of the wider world, and the film meets people from across the globe whose lives now orbit around the road. Their poignant stories of loss and the search for belonging are woven together into a rich tapestry of human experience.
