For years, advertising guru and SMU professor Willie Baronet has been fascinated by the signs the homeless use encouraging one to help. His artistic eye and agency background saw more than a plea - he saw art, he saw life, he saw humanity. Embracing his desire to create a 'HeART' project, Willie drives cross-country for a month - all the while "buying" the signs of the homeless he meets along the way. From Seattle to San Diego, Vegas to Cincinnati, Philly to New York, and points in between. Visiting with the people from whom he buys the signs, Willie meets a cross-section of America. Their common ground - they have no home. SIGNS OF HUMANITY follows Willie and his team throughout this trek. They start in Seattle not knowing what they are going to find or whom they are going to meet. Their sole desire - to collect these signs, talk to the homeless, and seek to discover: "what does home mean to you?".
