His two daughters exist alongside him in a strange region that has recently succumbed to a bizarre malady of mysterious origin. Following a series of encounters with a Chinese billionaire desperate to contract the disease, an obnoxious neighbour, and a sousaphone player in search of his band mates, the malady threatens to return. The social order, already precarious, crumbles as the virus takes hold once again.
