A disabled veteran with odd habits, Uncle is prone to drinking,hoarding and gorging, not to mention the occasional excursion down into the plumbing, where he might disappear for days ata time. As the world begins to shut down, Uncle and his niece are forced even closer still. She starts to watch his every move- every bathroom break he takes, every pill he swallows - and finds herself relying on this man, her only companion.
