To what extent does the presence of others affect our thoughts and actions? What do we believe when we are truly alone? Solitude is the riveting tale of diverse individuals isolated in a San Francisco seemingly void of all other human life. In the absence of others, each journeys into personal web of beliefs and perceptions as they try to determine what happened to them, and the world around them. Each of them view events differently. One suspects aliens have invaded, another believes it's a sign of Revelation and end times, some don't know what to think, and others find their minds unraveling as they struggle to cope with unimaginable events. Soon, threats both natural and supernatural leave them too busy fighting to survive in a world of strange and unpredictable events where all of the luxuries of civilization are being slowly eroded to even stop to wonder. And unless they can find each other, they will have to face it all alone, in the dark.
