That went better than planned. I set a goal of one page tonight, and wrote two and a half with little effort. I know my story is about a house under construction, an architect, and ghosts. I also know that my story will be based partially on the Orpheus and Eurydice myth. My working title is "The Ghost Builders". I glanced over a couple of sample screenplays, and have a screenwriting book I'll read before bed. I also wrote my one sentence summary:

A builder comes to believe that he can force a famed architect to reunite him with his dead wife.
