Part of it is timing, with the film getting its PBS premiere on the heels of The Sun exposing Pugh’s “Healthy Holly” deals with the University of Maryland Medical System, where she was a member of the board, and other businesses and people. Seeing how hard some unsung heroes, like those featured in the film, work and how fervently they keep the faith in Baltimore even as their leaders betray it makes my head feel like it is going to explode each time I watch or write about “Charm City.”
