Blindness

A driver waiting at the traffic lights goes blind. An ophthalmologist tries to diagnose his distinctive white blindness, but is affected before he can read the textbooks. It becomes a contagion, spreading throughout the city. Trying to step the epidemic, the authorities her the afflicted into a mental asylum where the wards are terrorised by blind thugs. And when fire destroys the asylum, the inmates burst forth and the last links with a supposedly civilised society are snapped.

No food, no water, no government, no order. This is not anarchy, this is blindness.
