​​In July 2020, Rob Bliss, a young, white filmmaker, posted a video of what happened when he held up a ‘Black Lives Matter’ sign in Harrison, Arkansas, ‘the most racist town in America’. It went viral, attracting 12 million views. What Bliss did next was remarkable. Over 1500 miles, two months and 25 miles a day, he set out to walk through the American South, wearing a Black Lives Matter t-shirt, and a sign that invited people to ‘come walk with me’. His goal was simple: to take the conversation Floyd’s murder had sparked about racism in American society into the places where it was most needed, yet most silent.
