When a big city has a mysterious outbreak of blindness, the victims are quarantined by the government in a hospital without any medical care, treatment or hygiene. Among the first people affected by the so called "white blindness" are an ophthalmologist and his reluctant health wife that has not lost her sight but stays with him to help him in the difficult moment. The place immediately crowds and a group of criminals takes the power, demanding jewels and electronics first and sex later for the limited ratio of food they control.
