Where are the hundreds of millions of people living with a severe mental illness? Over the past four years, Costanza, Bea, Tessi, and Arvind have connected with a group of people scattered across the world who have chosen to confront and support one another, sharing a common struggle against social stigma and the extreme isolation caused by mental illness. BKS documents the experience of a community breaking the silence to open up a new dialogue. To change the narrative, the first step is to start talking about it.
