But this year the heatwave is fiercer than usual, and the city's inhabitants have fled to the cool of the hills and beaches of the surrounding countryside. So, it is no surprise that amidst the shrubbery of a normally busy roundabout, a corpse lies unnoticed, bloating in the humid air.

The former policeman turned private detective has a case: a man who seems to have vanished into thin air-leaving his pregnant young wife alone in the city. Meanwhile, bank teller Roxana Delfino is also stuck in the city for the season, with nothing to do but worry for her aging mother and puzzle over the disappearance of one her regular clients.
