Dumpster tells the story of what happens when Jim, a janitor on the campus of an elite university, discovers Francis, a wealthy frat boy, hiding in a mobile garbage bin. Jim wrestles with adult responsibilities at home with his girlfriend and her child, while Francis struggles to overcome his roommate's suicide, getting 'dumped' by his girlfriend, and outgrowing the fraternity scene. Their late-night meetings at the Dumpster allow them to shed their labels and uniforms and find out how the other half lives, while discovering some good stuff in the dumpster.
