Premise: "How about a superhero serial killer?"

         John Dusk is a veteran superhero in a world where super-humans are a 
         sanctioned arm of law enforcement, facing the same rules, restrictions 
         and frustrations as any cop. After being pushed too far, he crosses the 
         line no cop is supposed to... and it feels good. He wants to keep doing 
         it, even though he knows it puts him on a collision course with his 
         teammates, friends and his girlfriend, a homicide detective.

         He's not crazy.

         He knows it's wrong.

         He wants to be forgiven...

            ... but he does not want to stop.
