In a small seaside town on the French coast lives Uncle. He shares his house with his niece and nephew, who look after him when they could be doing something – anything – else. 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 at a 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.
