Whole Day Down documents the reinvention of Willie Garson and Patrick Breen, two failed, middle-aged actors, as they pursue their mutual passion for art by opening a gallery. Limited to one Monday a month, in a space owned by Patrick's dictatorial Father-in-Law, our heroes must overcome a vindictive art critic out for blood, a satanic receptionist, a bizarre love pentagon and a roster of unorthodox and often difficult artists. So inevitable are their failures it becomes clear darker forces are at play and their innocent forays into the art world may be a harbinger of the coming Apocalypse.
