On an island an old man wracked with dementia dreams he was once a king. Together with his two duaghters they exist in the wake of a bizarre malady of mysterious origin, their surroundings remain mysteriously devoid of animal life. His youngest obsessively builds rubble walls around her father's hermitage in strange megalithic-type configurations in a feverish attempt to stave off a return of the virus.
Following a series of encounters with an obnoxious neighbour, a Chinese billionaire desperate to contract the disease and a sousaphone player in search of his band mates, the malady appears to return. The social order, already precarious, crumbles as the virus takes hold once again.
