A documentary film featured in this year’s Aspen Filmfest uses a chaotic emergency room to highlight the country's overloaded health care system. Code Black follows a group of young, idealistic E.R. residents who work in what seasoned doctor’s call “C-Booth” at Los Angeles County hospital. Aspen Public Radio's Marci Krivonen spoke with Ryan McGarry, an E.R. doctor and the director of the film.
