Sunset/Death - A synopsis

We're trying for investment on a film- here is a synopsis:

When a common "mindset" becomes a reality, Grady, an everyman, is left isolated and guilty. Set in a hauntingly familiar alternate reality, he encounters complex and life threatening situations that test the very thing that makes us who we are. Everyday his struggle to live battles his willingness to go on.

What does life matter to a person inflicted with the internal perspective of insignificance?
